Noah Lyles edged Kishane Thompson in a dramatic photo finish to take the Olympic title in the men's 100m sprint in Paris.

Lyles did not look to be in contention, but a late surge saw him cross the line in 9.79 seconds, just five-thousandths of a second ahead of the Jamaican.

It was a personal best for the American, who successfully began his bid to win four medals at the Paris Olympics, even after a delayed start to the race

Thompson, who narrowly won the silver medal, was locked in a tight battle with Lyles' compatriot for much of the race, with Fred Kerley taking bronze in 9.81.

He pipped South Africa's Akani Simbine to the podium in the tightly contested race, with all eight finalists finishing within 0.12 seconds of Lyles.
