Russia orders Ukrainian forces in Mariupol to surrender by Sunday morning

CNN: Russia has demanded Ukrainian forces still fighting to defend the besieged city of Mariupol lay down their weapons. The apparent ultimatum comes as Russia continues its relentless and devastating attack on the southeastern city.

Russian state media Ria reported that "without exception" all "Ukrainian armed units and foreign mercenaries" must exit from 6:00 a.m. to 1:00 p.m. Moscow time (same as local time) "without any weapons and ammunition," citing the Russian Defense Ministry.

An estimated 100,000 people remain in Mariupol and its immediate surroundings, which are reported to be largely under Russian control, with Ukrainian troops confined to pockets of resistance.

Some context: Ukrainian President Volodymyr Zekensky late Saturday called the situation in the besieged city of Mariupol "inhuman," saying the situation remained "as severe as possible."

"Russia is deliberately trying to destroy everyone who is there in Mariupol," he said in his latest video address.
