KYIV, UKARINE, APRIL 23

Another mass grave has been found outside Mariupol, the city council and an adviser to the mayor said Friday.

The city council posted a satellite photo provided by Planet Labs showing what it said was a mass grave 45 meters (147.64 feet) by 25 meters (82.02 feet) that could hold the bodies of at least 1,000 Mariupol residents.

It said the new reported mass grave is outside the village of Vynohradne, which is east of Mariupol.

Earlier this week, satellite photos from Maxar Technologies revealed what appeared to be rows upon rows of more than 200 freshly dug mass graves in the town of Manhush, located to the west of Mariupol.

The discovery of mass graves has led to accusations that the Russians are trying to conceal the slaughter of civilians in the city.
