sirens when we spoke to you last. >> reporter: well, i'll give you an update. friday night we were on the air for your show and heard these two booms and i spent the next sort of 12 hours trying to figure out what it was and it wasn't until the next morning russia announced they fired hyper sonic missiles we were able to put the timing together. that's what we heard the first ever use of these hyper sonic missiles flying over us on the way to targets in the west and this geopolitical discussion what the aim of that was. maybe russia was sending a message to the u.s. here in the western part of the country, the message is these missiles fly really fast. air can't pick them up and they're hitting the target. it's changed the way this city is operating. you see more sandbags and people headed for shelters when the sirens go off. in the eastern part of the country, you're looking at video from mariupol. this is a city being wiped off the map. the russians put together this weird offer of a surrenderer that really didn't mean anything because frankly, there is nothing to surrenderer. you have in this city the front lines are now over lapping.
