Casualties in south Russia blast

A car bomb has caused casualties in Nazran, the main town in Russia's southern republic of Ingushetia.

Russia's Itar-Tass news agency quoted local security officials as saying four people had been injured in the blast on Monday, including two policemen.

The blast occurred near a bank - Rinkombank.

Ingushetia, in the North Caucasus, has been plagued by violence for years. It borders on Chechnya, where separatist militants oppose Russian rule.
