New satellite imagery from near the besieged city of Mariupol in Ukraine shows an extended mass grave, the commercial company that took those photos said, according to Reuters.

Maxar Technologies said Thursday that a review of its images from mid-March through mid-April indicates the expansion of a mass grave to contain more than 200 new graves. The expansion began between March 23 and March 26, and it is located near an existing cemetery in the village of Manhush, which is slightly more than 10 miles outside of Mariupol.
