Ukrainian channels, based on the accumulation of data from Russian channels, claim an extremely large-scale drone attack, up to 1,000 units, although this is probably an overestimate.
The refinery in Volgograd is already on fire, but these are minor things, it is close to the border, and would have burned anyway. More interesting are other goals: Moscow or a breakthrough somewhere deeper.
It seems that Ukraine is using a new tactic in recent days, in which they launch drones every two days, but in large numbers. For example, yesterday there were almost no launches, the day before yesterday there was a big attack on Ost-Luga and not only that, the day before there were also almost no launches.
