Ukrainian drones force one of Russia's largest refineries to halt after strike hits key unit
A Ukrainian drone strike damaged the AVT-3 primary processing unit at the Slavneft-Yaroslavnefteorgsintez (YANOS) refinery near Yaroslavl, about 250 km northeast of Moscow, forcing the plant to halt crude oil processing on 17 September. AVT-3 accounts for roughly 40% of the refinery's capacity, and a second large unit was already offline from an earlier strike. Fuel from the plant disappeared from Russia's domestic commodity exchange the same day.
