Shots fired at U.S. Consulate in Istanbul

TURKEY -- Two assailants opened fire at the U.S. Consulate building in Istanbul on Monday, touching off a gunfight with police before fleeing the scene, CBS News correspondent Holly Williams reports.

One of the assailants - a woman - was injured in the crossfire and captured inside a nearby building where she hid. She was later identified as 42-year-old Hatice Asik, a member of the banned leftist group Revolutionary People's Liberation Army-Front, or DHKP-C. No one else was injured in the attack.

Hours earlier, an overnight bombing at a police station in Istanbul injured 10 people. Unknown assailants then fired on police who were inspecting the scene of the explosion, leaving 4 officers dead.

Williams reports the attacks came two weeks after Turkey agreed to take a more active role in the fight against Islamic State of Iraq and Syria (ISIS). Last month, Turkey conducted air strikes against ISIS positions in Syria and agreed to let the U.S.-led coalition use its bases for its fight against ISIS.

In July, Turkey began rounding up suspected militants, detaining some 1,300 people it said may have links to terror organizations, including the PKK, ISIS and DHKP-C.

DHKP-C was behind a 2013 suicide bombing at the U.S. Embassy in the capital Ankara that killed a Turkish security guard and injured one other person.
