Von der Leyen: 'the unthinkable has happened' in Bucha

STORY: Ukraine and several Western governments have accused Moscow of war crimes after the bodies of civilians shot at close range were found in the town of Bucha following a Russian withdrawal.

The Kremlin denies its forces were responsible for the deaths and said on Tuesday (April 5) that Western allegations Russian forces committed war crimes were a "monstrous forgery."

The European Commission chief and the EU's top diplomat arrived in Kyiv on Friday (April 8) to offer Ukrainian President Volodymyr Zelenskiy support and reassurance over his bid for EU membership in a capital gradually reviving after Russia pulled back forces.
