Ukrainian President Volodymyr Zelenskiy has urged the UN Security Council to seek full accountability for crimes that he says were committed by Russian forces in Ukraine.

Zelenskiy spoke to the council on April 5, providing graphic details of events that took place in the town of Bucha, where he said entire families were killed indiscriminately, particularly those who had served Ukrainian forces in some capacity.

People “were killed in their apartments, houses…civilians were crushed by tanks while sitting in their cars in the middle of the road, just for [the Russian soldiers’] pleasure. They cut off limbs…slashed their throats,” Zelenskiy told the 15-member council in a live video address.
