UPDATED Dec. 25, 2017, 11:04 a.m. ET It's back now. With little fanfare and zero explanation, Julian Assange's Twitter account reappeared on Monday morning. It's a Christmas something-or-other. The WikiLeaks founder has tweeted two times since his account came back online, though neither one addresses the reason for the disappearance. One tweet features a cartoon of Santa Claus adding WikiLeaks to his "Nice" list as he stares at the organization's Wikipedia entry. The other is a request for donations. It's still not clear why Assange's account went away to begin with, though — as noted below — the nature of its non-appearance suggested at the time that it was a manual deletion rather than an account suspension. Twitter had no comment on the matter, save for directing us to check out the company's instructions for users that want to deactivate and reactivate their accounts, which notes that "account data (such as Tweets, followers, favorites, etc.) may take a few minutes to fully restore." The big mystery may be that Assange (or whomever else has the keys to his account) accidentally clicked something and didn't realize it until later. Without a whistleblower, we may never know. Original post follows: WikiLeaks founder and notorious Ecuadorian embassy resident Julian Assange has seemingly deleted his Twitter account, throwing his supporters into a frenzy of speculation on Christmas Day. A search on desktop for his account, @JulianAssange, turned this up on Christmas morning: Image: screenshot/twitterThis would suggest that it was deleted on his end, rather than suspended by Twitter. When you search for a suspended Twitter account, it redirects you to a different message. We got this one by searching for twitter.com/JaydaBF, the far-right Britain First deputy leader Jayda Fransen who President Donald Trump retweeted. Image: screenshot/twitterMashable has reached out to Twitter for comment. In the meantime, speculation and conspiracy theories were trending in the UK on Christmas morning.  CENSORSHIP? Julian Assange Vanishes Off Twitter A source who works closely with WikiLeaks told the Gateway Pundit that they were not aware of any plans for Assange to deactivate his account on his own.https://t.co/U5fhIWRBYL — Cassandra Fairbanks (@CassandraRules) December 25, 2017 Now why would @Twitter ban Julian Assange when he was prepping to drop something big? Who is @Twitter trying to protect by this drop of information? — James Brower (@jbro_1776) December 25, 2017 Julian Assange was kicked of twitter today cuz he dared to expose the Dem party and the Clinton crime family. Let’s make this very clear. I have never tweeted about Seth Rich. But I believe we can now say, without a shadow of a doubt, the DNC/Clinton’s had him murdered. — Lawrence Polyakov (@Larrypolya22) December 25, 2017 According to the Wayback Machine internet archive, Assange's most recent tweet is from Friday. Image: screenshot/wayback machineWe will update this story as soon as we get more information. Assange can almost certainly avail himself of several other social media accounts: @WikiLeaks, and those of the cat who keeps him company in his embassy exile, @EmbassyCat and on Instagram. Assange has been living in the Ecuadorian embassy in London since 2012. He faces rape allegations in Sweden, which he denies, and is seeking asylum as he believes that if he leaves the embassy he will be extradited to the U.S. over WikiLeaks' publications.  UPDATED Dec. 25, 2017, 4:11 p.m. ET with Twitter's response to our comment request.

He's made his list, he's checked it twice, he already knows who's been naughty and nice. That's right: Santa Claus is coming to town – and you can follow him as he makes his way around the world. Every year, the boffins at Norad (the North American Aerospace Defense Command) kindly dedicate December 24th to tracking Father Christmas as he darts from chimney to chimney, country to country, and continent to continent, delivering gifts while voraciously consuming sweetmeats. Their service began by happenstance in 1955, when a Sears ad in a local paper offering the chance to speak to Santa mistakenly printed the top secret phone number of Conad – Norad’s predecessor. US Air Force Col. Harry Shoup took the first call from a young boy wanting to talk to Santa in good humour, and so a Christmas tradition was born. Now, every year, thousands of volunteers staff telephones and computers to answer calls and e-mails from children (and adults) around the world. As of 2007, search engine Google has also provided an online tracker, in partnership with Norad. Join us below to follow Santa's snow-flecked footsteps around the world.

Merry Christmas. Are you tracking Santa? Do you know where he is right now?” she asked.  She asked them if they made their lists and assured them that Santa is en route: “As soon as you go to sleep, Santa will be there.” She wished the kids and their parents a merry Christmas.  US President Donald J.

As such, Christmas day is not taken as a holiday in Thailand but many lights and decorations still adorn the streets of Thailand's capital Bangkok during the month to celebrate the King's birthday on 5 December.

Christmas Eve is a big deal for young Japanese couples, who treat the evening as we would do Valentines Day. No one is quite sure why the evening became an event for couples, but pop-star Tatsuro Yamashita’s 1988 song, “Christmas Eve” about the sadness of spending Christmas alone, popularised the romantic ideals of being close to that special someone on Christmas Eve.

Godspeed, Santa Claus. 11:31AM Urgent: Presents needed Are you just waking up to the realisation that it's Christmas Eve? Have you hitherto buried your head in the snow, unwilling to even countenance the idea that you might need to buy a semi-random assortment of objects for your friends and loved ones? Does the thought of a last-minute trip to the heaving High Street make you want to heave in an entirely different manner? Then fear not, because we've rounded up some gift subscription ideas that a) will make great presents, and b) can be bought from the comfort of your front room, without so much as the need to put on a pair of pants. Take a look at the below, and heave a sigh of relief. Last-minute Christmas gift guide: how to do all your shopping ... without going to the shops 11:30AM The wait is nearly over Well boys and girls, we're getting close. It seems that Santa is currently doing some last minute quality control. Here's a leaked image from his HQ in Greenland...   11:30AM Santa's journey in numbers Santa will travel an estimated 510,000,000km on Christmas Eve, which means he'll average 10,703,437.5km/hr, or about 1,800 miles per second. According to calculations in 2014, there are roughly 1.85bn children who can hope to receive presents. With an average of 2.5 children per household, that means Santa has to slide down 740m chimneys.  To hit those numbers, Santa needs to visit 390,000 homes per minute – or 6,424 per second. And what of the big guy's expanding waist line? Well, if each house places a 200ml glass of semi-skimmed milk and a mince pie by the fireplace, Santa will make his way throughy 148m litres of milk – enough to fill around 60 Olympic-size swimming pools – and chomp on 740m mince pies. As there are around 250 calories in a mince pie and 100 calories in the glass of milk, that means Santa will consume 259bn calories on Christmas Eve alone. Let's hope his trousers are elasticated. 11:30AM Fake news? A quick word on sources. This time last year, the Santa tracking world was split asunder by an apparent disagreement between the two main tracking organisations. While's Google's tracker reported its first sighting of Santa at 10am GMT, Norad's tracker lagged about 30 minutes behind. And it remained thus for the rest of the day: where one would see Santa arrive in, say, Madrid at 11pm GMT, the other would spot Santa in the same location half an hour later. Little has been said publicly about the confusion since then. The two organisations have apparently closed ranks after the division – leaving online conspiracy theorists to run amok. Are there two Father Christmases, sharing the burden of delivering gifts to every (good) child in the land? Was one tracker detecting an echo in time, the logical consequence of  the vertiginous speeds at which Santa must travel? Had Google picked up a genuine unidentified flying object? No one has the answers to these questions – but suffice to say that if the same happens again this year, we at The Telegraph will treat Norad's tracker as the official timekeeper. No disrespect, Google, but those guys have got the nukes... 11:29AM Why does NORAD track Santa? While we wait for Santa to file all the obligatory flight plans and put the finishing touches on his sleigh packing (we imagine he's much like any father on Christmas Eve right now, desperately pushing another bag of presents into a car boot that's already jammed full), let's take the opportunity to look back on how this Santa tracking business started. The year was 1955, and an advert promoting Santa's Toyland at the Sears department store had been published in the Colorado Springs newspaper, offering excited children the chance to speak to big man himself. The only problem? Rather than listing a dedicated Sears phoneline, the advert referenced a top secret hotline at Conad – Norad’s predecessor. The Sears advert that started it all Over at CONAD, all was calm and well, when US Air Force Col. Harry Shoup, director of operations at the nuclear missile base, noticed the red phone on his desk ringing. Col. Shoup had two phones, and you can imagine what the red one was for. "Only a four-star general at the Pentagon and my dad had the number," recalled his daughter Pam. Presumably fearing the worst, Col. Shoup picked up the receiver. Pam continues: "And then there was a small voice that just asked, 'Is this Santa Claus?'" Shoup was a straight-laced and disciplined man – much as you would expect for the director of operations at the US's nuclear HQ – and he reacted with due annoyance, suspecting he was the victim of a practical joke. But then the little voice started crying. "And Dad realised that it wasn't a joke," says Shoup's daughter. "So he talked to him, ho-ho-ho'd and asked if he had been a good boy and, 'May I talk to your mother?' And the mother got on and said, 'You haven't seen the paper yet? "'There's a phone number to call Santa. It's in the Sears ad.'" Shoup took the reins and ran with them. Soon, he was on local radio every hour, updating listeners on the whereabouts of an unidentified flying object that had the unmistakable look of a sleigh. From one small mistake, a tradition was born. Every year hence, the nuclear has run a Christmas Eve hotline for children, updating them on the whereabouts of the Great Benefactor In The Sky. The Norad Santa Tracking Operation HQ, in 2014 Over the years, Conad/Norad and Santa have proved to be a perfect fit. After all, who better to spot where Santa's sleigh is flying than a major operation dedicated to monitoring the skies? And what better way for the joint US-Canadian military division – men and women who routinely spent their time checking radar screens for signs of impending nuclear apocalypse – to spend their down time than talking to children about what they wanted for Christmas? In 2007, Norad partnered with Google to put the Santa tracking ritual online, and now children around the world can follow Santa's snow-flecked footsteps as he delivers presents during the night before Christmas. With the help of our live blog, of course. 11:29AM Good morning... ... and welcome to The Telegraph's Christmas Eve live blog, where we'll be tracking the movements of good ol' Santa (that's Father Christmas or even St. Nick to you and I) as he dashes around the world, delivering gifts and joy to all those children who have been well behaved over the course of the last 12 months. According to (un)official estimates, there's a while to go before Santa starts doing his thing. So, put the kettle on, get some breakfast inside you, fish out those dusty binoculars from wherever you left them this time last year, and get ready to join us for the ride.

After the presents, there is the turkey, but then how about a winter walk or maybe a film (and none of those slushy romantic ones please)? You could even book yourself into a mindfulness retreat if it's all become too much. We've wracked our brains for a range of activities to try out once Santa has done his job and all the presents have been ripped open.  How to keep the family entertained over Christmas 2:37PM Great wall of China Santa has just crossed over the Great Wall of China, which was built by the Qin dynasty to keep northern invaders out of their territories.  No such problems for Santa - nothing can get in the way of him and his reindeer tonight, they've got presents to deliver. Santa has a great view of the Great Wall #NORADTracksSanta thanks to @verizon for boosting our signal! pic.twitter.com/rEpRMxwkZW— NORAD Tracks Santa (@NoradSanta) 24 December 2017 2:20PM 1 billion presents delivered! A congratulations are in order for a certain Mr Claus, who has just dropped off one billion presents this evening. However with 6.6 billion more people still waiting for their pressies, Santa still has a long night ahead of him. 2:16PM Valentine's Day on Christmas Eve Santa is in Japan. Christmas Eve is a big deal for young Japanese couples, who treat the evening as we would do Valentines Day. No one is quite sure why the evening became an event for couples, but pop-star Tatsuro Yamashita’s 1988 song, “Christmas Eve” about the sadness of spending Christmas alone, popularised the romantic ideals of being close to that special someone on Christmas Eve. Meanwhile over here we're just thinking about all the pressies Santa is about to drop off. 2:02PM There's the Sydney Opera House It's flashback time. Here is Santa doing some sightseeing as he flys over some of Sydney's most famous landmarks. #NORAD spotted #Santa flying through Sydney, Australia! See the video! https://t.co/VwHzaTAGKO— NORAD Tracks Santa (@NoradSanta) 24 December 2017 1:54PM Have yourself a very smug Christmas Are you watching Santa scoot around the world safe in the knowledge that all your Christmas day plans are sorted? I bet you're feeling pleased with yourself, and so you should be. However, if you're still flying around frantically trying to tie up all the loose Christmas ends then have a read of our guide to having a smug Christmas, and catch a glimpse of how the other (more organised) half live? How to have a smug Christmas, in ten supremely self-satisfied steps 1:35PM White Christmas? Not in Australia Santa has touched down in Australia. No dreaming of a white Christmas here as it's the height of summer in Australia, with average temperatures of  30C However in 2010 the ssemingly impossible happened as 11 inches of snow fell in New South Wales just a few days before Christmas day. No such luck this year mind. 1:27PM Have you got Christmas dinner covered? While Santa is busy going around the world sorting out the presents, who is sorting out the turkey covered on the big day? We recommend you start your prep for the big Christmas day meal today and save yourself any extra stress on the day. You can prep the vegetables, make the stocks for the gravy and roll up your stuffing balls. Still feeling nervous about cooking Christmas dinner? Take a gander at our ultimate guide to cooking the perfect Christmas dinner. How to cook the perfect Christmas dinner 1:10PM We hope Santa has wrapped up warm Santa is currently flying over the Eastern tip of Russia with the temperature at -17°C. Chilly stuff - so make sure you put some warmed mince pies out on the side for when he eventually comes round to you. 1:02PM Change of Telegraph Christmas Elf That's me done for the year. Over to Richard Jones for more Santa tracking tracking... 12:41PM A peaceful place Santa is currently on his way to the Federated States of Micronesia, population 104,937, which we've previously listed as one of 16 countries that do not have an army. Can you guess the 15 others? 12:13PM The rise of the Christmas Eve box In case you haven't already heard, there's a new Christmas trend in town – and today is the day when it comes to fruition. The Christmas Eve box is a package full of small gifts that kids get to open the night before Christmas. Think of as an early bird's stocking, only without the connotations of mouldy feet. You can find out more about what to put in these boxes (there's still time to cook one up at home – though you'll need to get creative) by reading our useful guide. Ho ho ho, merry Christmas Eve. 11:41AM Q: Why is Rudolph's nose red? A: Because it's hotter than the sun. Here's some science from Norad, on how they use the heat from Rudolph's nose to follow their man... Santa spotted on DSP satellite from the heat off Rudolph's nose! https://t.co/ODGqIM3THR— NORAD Tracks Santa (@NoradSanta) December 24, 2017   11:31AM Eyes to the skies He's off! We have our first Santa spotting of Christmas Eve 2017, with Norad reporting that his red sleigh is currently zooming over Russia, en route to New Zealand and Australia.  Now that they've got Santa locked on their radar, you can follow his progress in the video at the top of this article. Godspeed, Santa Claus. 11:31AM Urgent: Presents needed Are you just waking up to the realisation that it's Christmas Eve? Have you hitherto buried your head in the snow, unwilling to even countenance the idea that you might need to buy a semi-random assortment of objects for your friends and loved ones? Does the thought of a last-minute trip to the heaving High Street make you want to heave in an entirely different manner? Then fear not, because we've rounded up some gift subscription ideas that a) will make great presents, and b) can be bought from the comfort of your front room, without so much as the need to put on a pair of pants. Take a look at the below, and heave a sigh of relief. Last-minute Christmas gift guide: how to do all your shopping ... without going to the shops 11:30AM The wait is nearly over Well boys and girls, we're getting close. It seems that Santa is currently doing some last minute quality control. Here's a leaked image from his HQ in Greenland...   11:30AM Santa's journey in numbers Santa will travel an estimated 510,000,000km on Christmas Eve, which means he'll average 10,703,437.5km/hr, or about 1,800 miles per second. According to calculations in 2014, there are roughly 1.85bn children who can hope to receive presents. With an average of 2.5 children per household, that means Santa has to slide down 740m chimneys.  To hit those numbers, Santa needs to visit 390,000 homes per minute – or 6,424 per second. And what of the big guy's expanding waist line? Well, if each house places a 200ml glass of semi-skimmed milk and a mince pie by the fireplace, Santa will make his way throughy 148m litres of milk – enough to fill around 60 Olympic-size swimming pools – and chomp on 740m mince pies. As there are around 250 calories in a mince pie and 100 calories in the glass of milk, that means Santa will consume 259bn calories on Christmas Eve alone. Let's hope his trousers are elasticated. 11:30AM Fake news? A quick word on sources. This time last year, the Santa tracking world was split asunder by an apparent disagreement between the two main tracking organisations. While's Google's tracker reported its first sighting of Santa at 10am GMT, Norad's tracker lagged about 30 minutes behind. And it remained thus for the rest of the day: where one would see Santa arrive in, say, Madrid at 11pm GMT, the other would spot Santa in the same location half an hour later. Little has been said publicly about the confusion since then. The two organisations have apparently closed ranks after the division – leaving online conspiracy theorists to run amok. Are there two Father Christmases, sharing the burden of delivering gifts to every (good) child in the land? Was one tracker detecting an echo in time, the logical consequence of  the vertiginous speeds at which Santa must travel? Had Google picked up a genuine unidentified flying object? No one has the answers to these questions – but suffice to say that if the same happens again this year, we at The Telegraph will treat Norad's tracker as the official timekeeper. No disrespect, Google, but those guys have got the nukes... 11:29AM Why does NORAD track Santa? While we wait for Santa to file all the obligatory flight plans and put the finishing touches on his sleigh packing (we imagine he's much like any father on Christmas Eve right now, desperately pushing another bag of presents into a car boot that's already jammed full), let's take the opportunity to look back on how this Santa tracking business started. The year was 1955, and an advert promoting Santa's Toyland at the Sears department store had been published in the Colorado Springs newspaper, offering excited children the chance to speak to big man himself. The only problem? Rather than listing a dedicated Sears phoneline, the advert referenced a top secret hotline at Conad – Norad’s predecessor. The Sears advert that started it all Over at CONAD, all was calm and well, when US Air Force Col. Harry Shoup, director of operations at the nuclear missile base, noticed the red phone on his desk ringing. Col. Shoup had two phones, and you can imagine what the red one was for. "Only a four-star general at the Pentagon and my dad had the number," recalled his daughter Pam. Presumably fearing the worst, Col. Shoup picked up the receiver. Pam continues: "And then there was a small voice that just asked, 'Is this Santa Claus?'" Shoup was a straight-laced and disciplined man – much as you would expect for the director of operations at the US's nuclear HQ – and he reacted with due annoyance, suspecting he was the victim of a practical joke. But then the little voice started crying. "And Dad realised that it wasn't a joke," says Shoup's daughter. "So he talked to him, ho-ho-ho'd and asked if he had been a good boy and, 'May I talk to your mother?' And the mother got on and said, 'You haven't seen the paper yet? "'There's a phone number to call Santa. It's in the Sears ad.'" Shoup took the reins and ran with them. Soon, he was on local radio every hour, updating listeners on the whereabouts of an unidentified flying object that had the unmistakable look of a sleigh. From one small mistake, a tradition was born. Every year hence, the nuclear has run a Christmas Eve hotline for children, updating them on the whereabouts of the Great Benefactor In The Sky. The Norad Santa Tracking Operation HQ, in 2014 Over the years, Conad/Norad and Santa have proved to be a perfect fit. After all, who better to spot where Santa's sleigh is flying than a major operation dedicated to monitoring the skies? And what better way for the joint US-Canadian military division – men and women who routinely spent their time checking radar screens for signs of impending nuclear apocalypse – to spend their down time than talking to children about what they wanted for Christmas? In 2007, Norad partnered with Google to put the Santa tracking ritual online, and now children around the world can follow Santa's snow-flecked footsteps as he delivers presents during the night before Christmas. With the help of our live blog, of course. 11:29AM Good morning... ... and welcome to The Telegraph's Christmas Eve live blog, where we'll be tracking the movements of good ol' Santa (that's Father Christmas or even St. Nick to you and I) as he dashes around the world, delivering gifts and joy to all those children who have been well behaved over the course of the last 12 months. According to (un)official estimates, there's a while to go before Santa starts doing his thing. So, put the kettle on, get some breakfast inside you, fish out those dusty binoculars from wherever you left them this time last year, and get ready to join us for the ride.
