Seven people have been killed in a bomb attack in southern Russia, including a senior police officer. Dzhabrail Kostoyev, the deputy head of the interior ministry in the southern region of Ingushetia, died along with two of his bodyguards and four civilians.
Two assassination attempts against him last year had failed. Violence has spilled over into Ingushetia and other regions from neighbouring war-torn Chechnya in recent years . Rebels have pledged total war against police in the North Caucasus, saying they are collaborating with Russian occupiers. Hundreds of people have been killed in suicide bombings in Russia since the start of the war with Chechnya in 1999.
The latest bombing coincides with the killing of the governor of a detention centre in the Karachayevo-Cherkessia region by unknown gunmen.
