sort of loudspeaker system, some sort of siren system here and kharkiv. this is the second largest city in ukraine. we have not heard the loudspeakers, we have not heard any sirens going off. so so far, those blasts that we are hearing, they are definitively some sort of boom or blast. they are unexplained, we are not seeing any movement on the street, we have a pretty commanding position, right next to the central square in the city. and we are not hearing anything, we are not seeing anything, we are just hearing those booms in the distance. again, we really have to wonder, and we will have to get some clarity on exactly where that happened. but it was chilling that we started hearing those booms only minutes after vladimir putin delivered that speech, to an audience in russia. who are still asleep, it was nighttime essentially there, just very early morning. it was almost as if the moment that he dropped his hand, his forces started their assault on the country.
