The outcome of the US presidential election is on a knife-edge, with Donald Trump and his rival Joe Biden neck and neck in key swing states.
Although prediction swings are titled towards Biden court, millions of votes remain uncounted and no candidate can credibly claim victory yet. there is no evidence of fraud.
Mr Trump, a Republican, claimed to have won and vowed to launch a Supreme Court challenge, baselessly alleging fraud while Biden, a Democrat, said he was “on a track to victory.”
The US is on course for the highest electoral turnout in a century. More than 100 million people cast their ballots in early voting before election day, and tens of millions more added their vote on Tuesday.
With the nation on edge, the final result may not be known for days.
The result so far, however, shows Trump impressive performance on pre-election than predicted, but Biden is still in the race and the overall result is not yet clear.
In the US election, voters decide state-level contests rather than an overall, single, national one.
To be elected president, a candidate must win at least 270 votes in what is called the electoral college. Each US state gets a certain number of votes partly based on its population and there are a total of 538 up for grabs.
The incumbent president is projected to have held the must-win state of Florida – a major boost to his re-election bid.
The BBC projects Mr Trump will win another conservative sunbelt state, Texas, where the Biden campaign had dreamed of an upset victory.
But Mr Biden could snatch Arizona, a once reliably conservative state. Fox News and the Associated Press have projected Mr Biden will win that state and CBS News, the BBC’s US partner, says it is leaning the Democrat’s way.
A loss for Mr Trump in that previously Republican-voting state would be a potentially serious setback.
The Rust Belt battlegrounds of Pennsylvania, Michigan and Wisconsin – which propelled Mr Trump to the White House four years ago – are very close.
Pennsylvania is considered crucial for Mr Trump if he is to stave off defeat – he has a significant lead there but a large number of mail-in ballots are yet to be counted. Mr Biden has a narrow lead in Wisconsin and the two are almost neck-and-neck in Michigan.
Georgia and North Carolina are also very close, though leaning Mr Trump’s way.
Mr Trump will keep hold of Ohio and Missouri, known as bellwether states because they have so often predicted the eventual winner, according to the BBC’s projection.
Mr Trump is also projected by the BBC to win Nebraska, though Mr Biden picked up one vote there in the electoral college, which could turn out to be crucial.
No surprises have emerged yet in the other states.
Control of Congress – the two-chamber legislature – is also at stake. As well as the White House, Republicans are crying to hang on to a majority in the Senate.
