Explosions have taken place at a Russian ammunition depot east of Moscow, the country's defence ministry has said.
The blasts occurred in an ammunition warehouse at a defence facility in the western Vladimir region on Tuesday. The site is believed to be a key ammunition storage site for the Russian army.
Russia's military blamed the blast on ammunition which had detonated after the storage building caught fire due to a "violation of safety requirements".
A state of emergency has been declared in the Kirzhach district and residents of nearby villages have been evacuated.
