US President Donald Trump "accepted" Russian leader Vladimir Putin's assurance that Moscow did not meddle in America's election, Russia's Foreign Minister Sergei Lavrov said Friday, after the closely scrutinised first meeting.

"President Trump said he heard clear statements from Putin that (the allegations of meddling) are not true, and that Russian authorities did not intervene, and he accepted these declarations," said Lavrov, who sat in the power meet between the US and Russia leaders.
