Fourteen villages have been evacuated and a motorway closed after a huge blaze at an ammunitions depot south-east of the Russian capital, Moscow.
At least six people have been injured, with five requiring hospital treatment.
The depot in the Ryazan region is reportedly used to store missiles and other artillery munitions. The site caught fire on Wednesday after flames spread from burning grasslands, officials said. A state of emergency has been declared in the region.
The emergency services reported a string of explosions from the depot site – coming every five to ten seconds – shortly after the fire broke out at about 13:40 local time (10:40 GMT). In footage shared by Russian media, loud bangs can be heard as columns of thick smoke rise above the site.
