Islamic insurgents in Russia's volatile Chechnya region stormed the parliament building, Tuesday, killing six people and injuring more than a dozen others.

At least two police officers died in the attack, along with three of the militants. Seventeen people were hurt.

Officials said one of the insurgents set off a suicide bomb at the gates of the parliament complex. At least two others ran into the building shouting, "Allahu akbar" ("God is Great" in Arabic) as they opened fire.

Chechnya and surrounding areas in North Caucasus have been battling an Islamist insurgency for years.

Last month a suicide car bombing killed 17 people and wounded more than 140 in Vladikazkav, a regional center in the North Caucasus.
