“This may have been unintentional,” Canadian Prime Minister Justin Trudeau said at a press conference in Ottawa.

“There is now a body of information that the flight was shot down by an Iranian Surface to Air Missile. This may well have been unintentional. We are working closely with Canada and our international partners and there now needs to be a full, transparent investigation,” British Prime Minister Boris Johnson said in a statement.

“The UK continues to call on all sides urgently to deescalate to reduce tensions in the region,” the statement added.

Trudeau has called for a thorough investigation into what caused the crash but would not provide additional details about the evidence and intelligence he cited.

CNN reported earlier Thursday that the US increasingly believes Iran mistakenly shot down the airliner, according to multiple US officials. The working theory is based on continuing analysis of data from satellites, radar and electronic data collected routinely by US military and intelligence.

A US official familiar with the intelligence said the plane was shot down by two Russian made SA-15 surface to air missiles. The US saw Iranian radar signals lock onto the jetliner, before it was shot down.

Initial exit polls predicted that Johnson’s Conservative Party would win 368 seats in the country’s 650-seat lower chamber, while Labour would pick up just 191 seats — which would give the Tories a majority of 86. As the night went on, U.K. broadcasters updated their forecasts to suggest that that majority could be slightly lower, possibly around a 76-seat majority.

Whatever the eventual number will be, it will mark a significant victory for the Tories, and a historic drubbing for the Labour Party of a kind they haven’t seen since the 1930s.

The night saw shock after shock as traditional Labour areas such as Burnley, Redcar, Stoke-on-Trent and Wrexham — with some seats that have been held by the party for decades — turn to the Conservatives. Many of those seats, often in working-class areas, had voted in favour of Britain’s departure from the European Union in 2016 and had soured at the Labour Party’s anti-Brexit stance

Johnson had called an early election to break the deadlock over Brexit, asking the British public to give him a majority so he could get his withdrawal agreement — negotiated with the E.U. — through the chamber, where it previously had been rejected. His message to voters tired of the drama since the 2016 referendum was simple: “Get Brexit done.”

As the results came in, Johnson declared that his party had been given “a powerful new mandate.”

“I’d like to thank the people of this country for voting in a December election that we didn’t want to call, but that I think has turned out to be an historic election that gives us now…a chance to respect the democratic will of the British people, to change this country for the better and to unleash the potential of the entire people of this country and this is what we will now do,” he said.

Johnson faced off against Corbyn’s Labour Party, which had struggled to lay out a clear vision for Brexit, backing a possible second referendum while also promising to get a new deal with the E.U. — but with Corbyn not committing to supporting that eventual deal.

Using the trending Twitter hashtag “#dogsatpollingstations,” voters were showing up to the polls Thursday with their best pals posting photographic evidence of the experience on social media.

“Forget politics, this is the main reason to log onto Twitter today,” one Twitter user joked. “Delighted to announce there were dogs at my polling station this morning,” another tweeted.

Prime Minister Boris Johnson, of the Conservative Party, joined in on the fun when he brought his dog, a Jack Russell cross named Dilyn, to vote with him in London.

Sadiq Khan, the Labour Party’s mayor of London, also brought his pooch named Luna to the polls and posted a video online encouraging people to vote.

Some dogs went to the polls dressed up — in fun costumes from a bumblebee to Santa Claus — while other dogs’ owners announced who they were voting for online.

It was not immediately clear how many dogs actually got inside voting booths. According to the electoral commission’s rules, animals, “apart from assistance dogs, are not usually allowed inside polling stations so will need to be secured outside if you do decide to take them with you.”

It is hoped Thursday’s election, which is being held more than two years ahead of schedule, will break Britain’s political impasse over Brexit and determine its future relationship with the European Union. Additionally, all 650 seats in the House of Commons seats are up for grabs.

Trump was interviewed by phone on Thursday by Nigel Farage, leader of the Brexit party and rival of Johnson in the upcoming election on December 12.

The president said that a U.S.-U.K. trade deal would be impossible under the current terms of Brexit, which Johnson reached with the European Union.

“We want to do trade with the U.K. and they want to do trade with us. And to be honest with you, this deal, under certain aspects of the deal, you can’t do it,” Trump told Farage on his radio show on London station LBC, according to the Wall Street Journal. “You can’t trade. We can’t make a trade deal with the U.K.”

The British government, however, has said that under Johnson’s Brexit agreement, the U.K. would be removed from the EU’s customs area and it would be free of the EU’s regulations, allowing it to sign bilateral trade deals with the U.S. and other countries.

Trump’s appearance on Farage’s show sends a mixed political signal, as Trump and Johnson have typically been closely aligned. Johnson’s left-wing rival, Jeremy Corbyn, accused him in August of intending to lead the U.K. “straight into the arms” of Trump. Farage’s Brexit party criticizes Johnson from the right, calling for an abrupt split from the union rather than any sort of agreement.

On Thursday, Johnson on Twitter accused Trump of “ trying to interfere in UK election to get his friend Boris Johnson elected” after Trump said that Johnson would be “so bad” for Britain if elected.

Britain agreed Wednesday to hold a general election on Dec. 12 in an effort to shake up Parliament and break the months-long Brexit stalemate. The European Union has extended Britain’s Brexit deadline to Jan. 31.

Even so, Trump said Johnson is a “fantastic man” who is “exactly the right guy for the times.” He said he’d like to see an electoral pact between Johnson’s Conservatives and Farage’s Brexit Party, saying the two together would be an “unstoppable force.” Neither party has indicated such a deal is on the table.

In previous attempts, two-thirds were required, however, the PM will publish a bill that would only require just a simple majority to be successful.

However, he would still need the full support of the SNP and Lib Dems for the bill to pass.

Labour said that Boris Johnson, the PM should not be trusted despite the prime minister telling MPs Parliament was “dysfunctional and could no longer keep this country hostage”.

Well short of the two-thirds majority the bill needed to be a success under the Fixed-Term Parliaments Act, the government’s election motion was backed by Commons by 299 to 70.

Along with the SNP and DUP, a greater majority of Labour MPs refused to vote even as all Conservative MPs were in full support of the Motion. However, all but just one Dem MPs voted against it.

The prime minister officially accepted the European Union’s offer of an adjunct to the Brexit process to January 31^st, then the vote came after.

The PM said the further three-month extension which he stood his ground was forced upon him by Parliament was “unwanted” according to the contents of a letter to EU officials.

Deshaud Williams, a 16-year-old sophomore at Lewisville High School, located in the Dallas-Fort Worth area, was in good health before his collapse, according to his family.

On Friday, Deshaud and his twin, Dashaud, were running and playing tag when suddenly Deshaud said he couldn’t breathe.

“He was like, ‘Da, I can’t breathe. I was like, ‘You good? Come on, we’re going to get home,” twin Dashaud told KXAS-TV. “He was like, ‘I can’t breathe. I’m about to pass out.’ And I ran to him and he fell to his knees and fell on his back.”

Dashaud called 911, but his twin brother died. His mother, Razel Sheppard, said his death is “a big mystery” considering he was healthy before he died.

“He’s never been sick. He was a healthy all-around kid. Hopefully, [we’ll] get answers,” she said. “His heart couldn’t take no more and he died in his brother’s hands.”

The Lewisville community is mourning Deshaud’s death. On Sunday, friends and family came together to honor him with a balloon release in his memory.

“Today our hearts are broken,” the school’s football team tweeted. “Please keep the Fighting Farmer community in your prayers as we mourn the loss of a student-athlete.”

Darren Johnson, a friend of Deshaud’s, described the teen as motivational, telling the news outlet: “When he was tired, we would pick him up. When we were tired, he would pick us up.”

“There was no better friend you could have,” Johnson said. “He’ll always be in our hearts.”
