Turkish police Thursday killed two female assailants who hurled grenades and opened fire at an Istanbul police station before taking cover inside a nearby building, Turkish media reports said.
The two women - whose identity and affiliation was not clear - had holed up in an apartment in the Bayrampasa neighbourhood of the megacity after their attack.
Police then launched an assault on the apartment, "neutralising" the two, the official Anatolia news agency said, quoting police sources. There were no reports of other casualties.
According to the Dogan news agency, the two women had thrown several grenades then opened fire at the riot police headquarters. Officers returned fire, injuring one of the attackers before they fled to the nearby building.
Turkey has been on a state of alert for months since a series of deadly attacks on its soil.
