A huge arms depot in a city in eastern Ukraine caught fire early yesterday morning. And it set off a bunch of MISSILES that started landing all over the city. Ukraine's military stores thousands of tons of rockets and artillery there, so it was massive.
About 20,000 people in a six-mile radius had to evacuate. No word on fatalities, but Ukraine's military claims it WASN'T an accident. Some people think the Russians set off a chain reaction by dropping an explosive device from a drone.
(The biggest explosion happens at 2:05.)
