At least three Russian soldiers were killed in a suicide bombing at a military base in restive Dagestan republic in the North Caucasus region early Sunday, DPA quoted media reports as saying. The ministry said five of the 32 people injured in the attack were in a critical condition, according to the Interfax news agency. The injured were flown to a hospital in the southern city Rostov-on-Don. The suicide bomber drove an explosives-laden car into a gate at the base, located about 2 kilometres north-east of Buinaksk city. Reports said around 50 kilograms of the explosive TNT was used in the bombing. Guards had reportedly prevented further fatalities by blocking the entrance. Another bomb exploded on the roadside when investigators arrived at the scene, without causing injuries, authorities said.
