Off any remaining peace talks, and now, mariupol would be a major one for vladimir putin and a chance for him to change the narrative after the sinking of the moskov and a victory ahead of the may 9th celebrations in russia that we talked about when they hold a military parade to mark the end of the second world war and strategically it would allow a land bridge between crimea which he annexed in 2014 and the separatist republics way out in the east of the country. the situation for civilians in mariupol, almost unimaginable. the mayor says at least 10,000 have been killed. the final toll may be much, much higher than that. there is almost no food, people have been drinking filthy water to survive. and an adviser to the mayor is saying, russian forces are now setting up checkpoints around the city, no one allowed in, no one allowed out, and men going through those checkpoints are being interrogated.
