Roadside bombs and gunfire killed six people and wounded five in Russia's North Caucasus region, officials have said, as a provincial leader remained in critical condition from an earlier suicide attack.
The president of the province of Ingushetia, Yunus Bek Yevkurov, has been kept on an artificial respirator in a Moscow clinic since he was wounded in a suicide bombing on Monday, but his life was not in immediate danger, said his spokesman, Kaloi Akhilgov on Wednesday.
Chechnya and Ingushetia share a border in Russia's volatile North Caucasus region, where a separatist Islamic insurgency mounts daily attacks on police and other officials -- an aftermath of two separatist wars in Chechnya over the last 15 years.
Chechnya's branch of the Russian Interior Ministry said a roadside bomb destroyed a car late Tuesday and killed two civilians it was carrying. Early yesterday, five police were wounded by a bomb hidden amid roadside garbage, it said.
In Ingushetia, a police officer was shot dead yesterday by unidentified assailants in a drive-by shooting, local prosecutor's office said. In a separate clash later, several gunmen riding in a vehicle opened fire at police who tried to check their identity papers. Police killed all three militants, the regional Interior Ministry's branch said.
Officials have blamed Islamic militants for the attack on Yevkurov, but no arrests have been made.
