Link? Like I say media don't talk about it. There are just photos which people share. My son make one. He, my ex wife and other son see this with his own eyes. Anyway there is not to much to see. Big drones and smoke - fog - trail behind them. In normal situations government - media talk about such stuff days before... when they dust against mosquitos. Because beekeepers must be informed. Also they never before use drones for this. Airplanes and vehicle's are used for dusting. btw. it's to early for dusting against mosquitos anyway. Also drones is strictly regulated in my country, size, weight, etc. Someone in government know about it, but no one talk, even "opposition" politicians..... like usual when they work together. PS. I don't live in Russia or Ukraine.
