Activists daubed a giant Ukrainian flag on the road outside the Russian embassy in London on Thursday to mark the anniversary of the Russian invasion.

Protest group Led By Donkeys posted an image of their work on Twitter, showing traffic driving over a road painted in blue and yellow.

"Tomorrow is the first anniversary of Putin’s imperialist invasion of Ukraine, an independent state and a people with every right to self-determination," tweeted the group.

"The existence of a massive Ukrainian flag outside his embassy in London will serve to remind him of that."
