northwest out of kherson to try to encircle odesa. they have ships in the black sea. we haven't seen any maritime moves on odesa, but it certainly seems to be what they are considering doing. it would make sense that if they did that they would also try to come up on a ground perspective coming down from the north, and that appears to be what they're trying to do or why they went through kherson. they've had more progress in the south, but in the north they continue to be frustrated. they're not making as much progress on major population centers, certainly not kyiv, not kharkiv, not a town called chernihiv which they're trying to encircle and bombard. that con vie we have been talking about has been stalled and slowed and a reason for that has been the ukrainian resistance. they were able to hit some of the lead vehicles and get it to stop. >> pentagon press secretary, retired rear admiral john kirby. thank you. you do a great job explaining this difficult situation. we appreciate it. >> thank you. joining us live from lviv,
