Russia launched a record 188 drones into Ukraine Monday night, advancing its attacks at its fastest pace in two years, according to an assessment from the Institute for the Study of War. Now, NATO and Ukrainian officials are convening an urgent meeting.

Russian forces are advancing in Ukraine at the fastest rate since the early months of the war, according to a respected US-based thinktank. Battlefield reports indicate Moscow is edging closer to the key logistics town of Pokrovsk in Donetsk.
