Gunmen open fire at Istanbul police station

Gunmen have opened fire on a Turkish police station in Istanbul, and fled the scene of the shooting attack, Turkish media reports say.

The assailants fired at least 10 bullets with long-barreled weapons at the building in the Sultangazi district of the largest city in Turkey on Tuesday morning, Cihan News Agency reported.

Security forces backed by a helicopter gunship have launched a massive manhunt to arrest the attackers.

On Monday, a demonstration was held in the city following a bomb blast in the town of Suruc. Turkish police fired water cannon to disperse the protesters.

The explosion in Suruc, located in southern Turkey near the Syrian border and opposite the Syrian town of Kobani, killed more than 30 people.

The explosion targeted people from the Socialist Youth Associations Federation, also known as the SGDF, who had gathered at a cultural center before their journey to Kobani to help in the restructuring of the war-ravaged town in Syria.
