Massive flames and plumes of smoke have lit up the night's sky with a series of enormous blasts reported across various Russian regions close to the Ukraine border in the early hours of Wednesday.
Explosions were heard in the city of Belgorod, said regional governor Vyacheslav Gladkov, and an ammunition depot in the province was on fire.
The province borders Ukraine's Luhansk, Sumy and Kharkiv regions, all of which have seen heavy fighting since Russia invaded Ukraine two months ago.
