A suicide bombing in Chechnya on Monday killed four people and injured three in the latest violence in the Russian region where the Kremlin fought two wars over the past 20 years.

Two officers, a soldier and a civilian died in the explosion when their armored vehicle travelling between the garrison town of Khankala and the capital Grozny made a stop, Vasily Panchenkov, a spokesman for the interior ministry troops, said.
Three more servicemen received serious injuries and were admitted to hospital, Panchenkov said.

He said the blast was detonated by a bomber with a suicide belt, adding that body fragments believed to belong to the attacker were found at the scene.

In separate statements, the Chechen interior ministry and Moscow-based investigators said however there were two suicide bombers.

The Moscow investigators said the servicemen were killed in two blasts detonated by two suicide bombers near the entrance to a store in Grozny.

Russia in 2009 formally ended a decade-long "counter-terror" operation in Chechnya, as it was claimed to be, citing the return of relative stability to the region.
