Russia operatives used an armed robot in a gunfight that left 11 jihadists dead - as they try to stamp out extremism ahead of the World Cup.

Counter-terrorism forces engaged extremists in the volatile Islamic region of Dagestan over several days.

Dramatic footage shows police marksman firing on a house from an armored vehicle.

A compact armed robot is seen approaching the property to engage the jihadists.

The bullet-ridden bodies of six men were later shown in pictures released by investigative authorities.

Video and audio recordings taken by the robot reveal the voices of rebels shouting 'Allahu Akbar', followed by an explosion, it was reported.

The men were also believed to have been waving a jihadist flag.

Derbent, where the video was filmed, is just 590 miles southeast of Volgograd, where England will play their opening World Cup qualifying group game.

The FSB security service has indicated terrorism is the main threat to the World Cup.

'Guns, bullets, knives and grenades were discovered at the scene,' said a statement from the Russian Investigative Committee, which probes serious crime.

A hand made bomb, equal in power to five kilograms of TNT, was discovered before the house went up in flames.

'Police shot back and all the attackers were liquidated at the scene.

'No police or civilians were injured during the incident.'

Senior Dagestan Interior Ministry official Sergei Karpov said: 'The militants eliminated in Derbent and the [surrounding] district were members of co-called sleeper cells.'
