An analysis of satellite images by The New York Times rebuts claims by Russia that the killing of civilians in Bucha, a suburb of Kyiv, occurred after its soldiers had left the town.

When images emerged over the weekend of the bodies of dead civilians lying on the streets of Bucha — some with their hands bound, some with gunshot wounds to the head — Russia’s Ministry of Defense denied responsibility. In a Telegram post on Sunday, the ministry suggested that the bodies had been recently placed on the streets after “all Russian units withdrew completely from Bucha” around March 30.

Russia claimed that the images were “another hoax” and called for an emergency U.N. Security Council meeting on what it called “provocations of Ukrainian radicals” in Bucha.

But a review of videos and satellite imagery by The Times shows that many of the civilians were killed more than three weeks ago, when Russia’s military was in control of the town.

One video filmed by a local council member on April 1 shows multiple bodies scattered along Yablonska Street in Bucha. Satellite images provided to The Times by Maxar Technologies show that at least 11 of those had been on the street since March 11, when Russia, by its own account, occupied the town.
