Extraordinary footage has emerged of the moment two female militants opened fire outside a Turkish police station and started throwing grenades.
The unverified video, aired by the Haber Turk network, appears to show two women dressed in everyday clothing pull out weapons are fire upon members of the public and a Turkish police bus as it arrived at the station.
CNN Turk reported that police returned fire, injuring one of the women, before they fled to a nearby apartment block.
Both women have now been shot dead by officers, after a brief siege was broken in a special forces raid. One officer was wounded in the arm in the process.
Footage on Turkish television stations showed the street cordoned off, before police in bullet-proof vests moved in and blew open the doors of the building.
In the earlier video, one woman can be seen firing what appears to be an uzi-style weapon, while the other throws apparent grenades from her bag. The second woman then pulls out a handgun and opens fire on an unseen target directly below the point where the video is being filmed.
Incredibly, Turkish media reports suggest no one was harmed in the attack itself.
There was no immediate claim of responsibility for Thursday's attack. The radical leftist group DHKP-C has repeatedly staged similar attacks on police stations, largely in Istanbul suburbs.
But attacks on the security forces have increased as violence flares in the country's predominantly Kurdish southeast, where a ceasefire between Kurdistan Workers' Party (PKK) militants and the state collapsed last July.
Turkey has also become a target for Islamic State militants, who are blamed for three suicide bombings - one last year in the town of Suruc near the Syrian border and another in the capital, Ankara, and one in Istanbul in January. Those attacks killed more than 140 people.Additional reporting by Reuters
