An oil depot in Luhansk in eastern Ukraine has exploded and caught on fire, with about 200 tons of diesel-burning as of Saturday night.

Luhansk authorities said people were injured, and that the explosion may have been caused by a rocket attack from Ukraine.

​​Eight years ago dozens of protesters were shot to death by riot police for demanding Ukraine’s government loosen ties with Russia and strengthen relations with Europe, and recent events have surfaced old memories.
