New satellite images show apparent mass graves near Mariupol, where local officials accused Russia of burying up to 9,000 Ukrainian civilians to conceal the slaughter taking place in the ruined port city that’s almost entirely under Russian control, writes ANC NEWS.

The images emerged just hours after Russian President claimed victory in the battle for Mariupol, despite the presence of an estimated 2,000 Ukrainian fighters who were still holed up at a giant steel mill. Putin ordered his troops to seal off the stronghold “so that not even a fly comes through” instead of storming it.

Satellite image provider Maxar Technologies released the photos, which it said showed more than 200 mass graves in a town where Ukrainian officials say the Russians have been burying Mariupol residents killed in the fighting. The imagery showed long rows of graves stretching away from an existing cemetery in the town of Manhush, outside Mariupol.
