Two attackers opened fire on the U.S. consulate building in Turkey's biggest city, Istanbul, on Monday and fled when police shot back, broadcaster CNN Turk said, as cited by Reuters.
The Cihan news agency said those involved in the attack on the building in Istanbul's Sariyer district included one man and one woman. Reuters reports.
CNN Turk said there were no casualties.
Turkey has been in a heightened state of alert since it launched what officials described as a "synchronized war on terror" last month, including air strikes against ISIS fighters in Syria and Kurdish militants in northern Iraq, and the detention of hundreds of suspects at home.
