so, you know, i don't think we're in any kind of direct risk at the moment, but in these situations you just take the precautions as you -- as best you can. >> yeah, of course, and things can change in a moment's notice. when you say things are about a kilometer away, and you are hearing them, that means they must be pretty significant? >> yeah, so what i believe we just heard is sort of a rolling rumble that you hear of multiple impacts at once is something the russian term for it is a smerch, which is a multiple launch rocket device that fires out a lot of different sort of impact warheads at once, that kind of land in a volley, not one specific impact like artillery or not. you can tell the difference between those. that's not uncommon. we've heard sporadic firing from those on the front lines and in some or the outskirts of the city. i was driving through some of those areas today.
