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.
Biden, a Democrat, said he was “on track” to victory, while Trump, a Republican, claimed “a big win”.
The president is projected to have held the must-win state of Florida a major boost to his re-election bid.
With the nation on edge, the final result may not be known for days as postal votes are tallied.
