This is the moment a suspected Islamist terrorist cell opted to blow themselves up rather than surrender to police.
Police had tracked the four extremists to a house in the village of Psedach in south western Russia’s Republic of Ingushetia, where they ordered the men to surrender.
However, rather than give themselves up, the group opted to set of a bomb which destroyed their hideout, killing all four of them.
The gang of extremists had been being hunted by the Russian secret services in connection with the attempted murder of policemen, local news reports.
Federal Security Service operatives surrounded their hideout, and the group began shooting at the officers, who returned fire.
Footage shows how the specialist troops began shooting at the property with rifles, machine guns and mortars.
Realising that the game was up, the militants then decided to blow themselves up rather than be captured.
