Ukrainian government and military officials in the southern port city of Mariupol say Russian forces have brought in mobile crematoriums to erase evidence of war crimes that are “much, much worse” than the reported atrocities in the liberated northern areas near the capital of Kyiv.

A planned evacuation of foreign nationals from Mariupol negotiated by Turkish President Recep Erdogan with Russian counterpart Vladimir Putin and scheduled to begin this past Sunday was abruptly halted before it began and only hours after it was announced, Russian state channel RIA News announced.
