Attack on convoy kills four in Russia's volatile south
An attack on a convoy in Russia's volatile North Caucasus region killed four members of Chechnya's security forces and wounded seven on Monday, news reports said.
A convoy carrying troops from Chechnya's interior ministry was ambushed around 1500 GMT in the neighbouring republic of Ingushetia, a police source told the Interfax news agency.
"Unidentified persons opened fire with automatic weapons and grenade launchers on a convoy of... Chechnya's interior ministry forces," the source said.
"According to preliminary information, four soldiers were killed and seven others injured," the source said, without providing further details.
The Kremlin has been fighting insurgents in the North Caucasus since the 1991 collapse of the Soviet Union, waging a war in 1994-1996 against separatist rebels in Chechnya.
After a second war in Chechnya in 1999, the rebellion's inspiration moved towards Islam with the aim of imposing an Islamic state in the region.
Although the war ended in 2000, rebels have waged an increasingly deadly insurgency, with the unrest spreading into other areas of the North Caucasus such as Ingushetia and Dagestan.
