VIDEO: Three killed in blasts in Russia's Belgorod

Explosions have killed three people and wounded four others in the Russian city of Belgorod, near the border with Ukraine, the region's governor has said.

The cause of the explosions is being investigated, but several Russian regions near the Ukrainian border have repeatedly accused the Ukrainian military of shelling civilian targets since Moscow began its invasion of Ukraine on February 24.

Kyiv does not usually comment on such accusations.
