KIEV (Reuters) – Around 12,000 people were evacuated after a fire and explosions at a rate of two to three a second hit a Ukrainian Defence Ministry ammunition depot early on Tuesday morning, officials said.

No casualties were reported.

Ukraine’s state security service said it was investigating possible sabotage, and the defense ministry’s spokesman said the fact that explosions were set off in different parts of the depot pointed to sabotage.
