British athletics legend Mo Farah won his 10th successive global title, winning the 10,000 metres world crown at the London Stadium where he won Olympic gold in 2012.
The 34-year-old, who will bid to add a third successive world double in the 5000m later in the championships, had a narrow escape from disaster on the final lap when he was clipped twice but somehow kept his balance to prevail.
Ugandan youngster Joshua Cheptegei of Uganda took silver and Paul Tanui of Kenya claimed bronze with Farah having once again foiled their respective nations' tactics.
"It makes me proud to be
British. It's been a long journey, it's been incredible," said Farah who was accompanied by his family on a lap of honour.
"It's been hard but I'm just mentally strong I guess."
He added: "It was amazing tonight, I had to get my head around it. I got a bit emotional at the start and then I just had to get in the zone. It has all been amazing.
"I knew at 12 laps to go when they went hard from there I knew it was going to be tough. It was about believing in my sprint finish and knowing that I have been in that position before. It helped a lot having that experience."
