Local officials in Mariupol say at least 10-thousand civilians could be buried in mass graves on the outskirts of the city.
The latest satellite images appear to show another pit, located next to a cemetery.
Yesterday it was revealed around 200 graves had been dug in a village nearby.
Local politician Dmytro Gurin explains what's been happening in the last few days:
"Bodies, that were massively on the streets, started to disappear. Nobody knew where Russian troops are taking these bodies; and now we know - in mass graves".
