The Ukrainian military hit the largest oil depot in Russian-occupied Crimea early Monday, causing a large fire at the facility.

The authorities in Crimea have reported that over 1,047 people have needed evacuation due to a fire at the oil terminal in Feodosia on the occupied peninsula. Russian media reported that more tanks exploded last night and in the evening.

Ukraine’s General Staff said on social media that the oil terminal in Feodosia, on the south coast of the Russia-occupied Crimean Peninsula, has been supplying the Russian army with fuel and that the strike was part of an ongoing effort to “undermine the military and economic potential of the Russian Federation.”
