An bomb mounted on a motorcycle exploded Thursday not far from Istanbul's Ataturk airport, wounding at least 10 people, Turkish officials said.

The blast unfolded outside a police station in the city's Yenibosna district, northeast of the airport, where people reported they could hear the explosion.

The victims were civilians, Vasip Sahin, the governor for Istanbul, told reporters at the scene. He said none of the injured was in serious condition, retracting an earlier statement that one person was seriously hurt.

Police were searching for one person spotted leaving the area on a motorbike, NTV television reported, citing unidentified security officials.

No groups immediately claimed responsibility for the blast. Turkey has been rocked by a wave of terror attacks in the past year carried out by Kurdish rebels or Islamic State group militants.

The Kurdistan Workers' Party, or PKK, has been targeting police and military in its campaign for Kurdish autonomy in southeast Turkey.

A fragile 2 1/2-year cease-fire between Turkey and the PKK collapsed last summer. Since then, more than 600 Turkish security personnel and thousands of PKK militants have been killed in clashes, according to the state-run Anadolu Agency. Rights groups say hundreds of civilians have also been killed in the clashes.

Video from local media showed several damaged cars, shattered windows and broken glass on the ground as police investigated.
