Two gunmen opened fire on the US Consulate in Istanbul in Turkey on Monday, according to initial reports. The attackers fled when police shot back, broadcaster CNN Turk said, adding that there were no casualties.
The attack followed a bombing at a police station in Istanbul earlier on Monday, which left at least five officers injured. Two civilians were also injured in the bombing, according to the International Business Times.
It is not yet known if the two incidents are connected.
The Daily Sabah reported that one of the suspects in the gunfire outside the US Consulate is a woman.
Al Jazeera reported that one of the police officers investigating the scene of the bomb blast at the police station has been shot at.
Turkey launched what officials described as a "synchronized war on terror" last month, including air strikes against Islamic State fighters in Syria and Kurdish militants in northern Iraq, and the detention of hundreds of terror suspects within Turkey.
The far-leftist Revolutionary People's Liberation Army-Front (DHKP-C) claimed responsibility for a suicide bombing at the US embassy in Ankara in 2013 which killed a Turkish security guard.
