“A bombing outside a planned performance by a dance company from the restive Russian republic of Chechnya left six people dead and more than 40 wounded on Wednesday, state media reported.

The bomb went off outside a community center in the southwestern Russian city of Stavropol, according to the Investigation Committee of the Russian Prosecutor’s Office, which called the explosion ‘an act of terror.’ The blast happened about 6.45 p.m. (10:45 a.m. ET), 15 minutes before the Chechen dance company Vainakh was scheduled to perform, the committee reported.

One of the dead included a preteen girl, according to state-run news agency RIA-Novosti.

“A suicide bomber has killed two policemen in an attack on a police station in Russia, the third terrorist outrage in the country in a week.

A third officer was wounded in the blast outside the police headquarters in Karabulak, in the North Caucasus province of Ingushetia.

“Two suicide bombers including one impersonating a police officer killed 12 people in southern Russia on Wednesday, two days after deadly suicide bombings blamed on the region’s militants tore through the Moscow subway system.

Prime Minister Vladimir Putin said Wednesday’s blasts in the province of Dagestan – which involved one bomber impersonating a police officer – may have been organized by the same militants who attacked the Moscow subway.

‘I don’t rule out that this is one and the same gang,’ Putin was quoted by Russian news agencies as saying at Cabinet meeting. The powerful former president previously vowed to ‘drag out of the sewer’ the terrorists who carried out the Moscow attacks, which killed 39 and injured scores more.

Bombings and other attacks occur almost daily in Dagestan, Chechnya and Ingushetia, provinces in Russia’s North Caucasus region where government forces are struggling against a separatist Islamist insurgency.

“Female suicide bombers detonated explosions that rocked two subway stations in central Moscow during rush hour on Monday morning, killing at least 35 people, officials said.

‘It was a terrorist act carried out by the female suicide bombers,’ said Moscow Mayor Yury Luzhkov, citing Russia’s intelligence agency, the Federal Security Service. ‘They were specifically timed — for … the train was nearing the station — to make the most damage.

‘The blast was caused by 300 to 400 grams of explosives,’ he said.

“Attackers have fired grenades at the interior ministry in Russia’s restive republic of Ingushetia.

At least one policeman was killed and others were injured in the attack on the building, which also houses the local police headquarters.

Several assailants fired around five grenades into the building before fleeing in a car after Monday’s attack in the regional capital Nazran.
