An explosion on a highway overpass near a subway station in Istanbul on Tuesday wounded five people and was caused by a bomb, a local mayor said.
The bomb was left on barriers on the overpass, said Atilla Aydiner, the mayor for Istanbul's Bayrampasa district. Earlier, Istanbul's governor said one person was slightly injured in the blast.
The explosion occurred at 5:30 p.m. local time at an overpass near the city's Bayrampasa subway station, on the European side of Istanbul. Several ambulances and police vehicles were sent to the area.
The Dogan news agency said it was a handmade cluster bomb. Dogan also obtained closed-circuit TV footage showing an explosion that looked like a fireworks display in the night sky. The agency's footage also showed a white van on the overpass, with large holes in its windshield, apparently damaged in the explosion. The Anadolu Agency identified an injured person as a 36-year-old man and said he wasn't in serious condition. It wasn't immediately clear whether he was in the vehicle at the time of the explosion.
Subway services at Bayrampasa and elsewhere were disrupted briefly following the explosion.
Kurdish rebels fighting Turkey for autonomy in the mainly Kurdish southeast area of the country have carried out bombings in Istanbul in the past. Fighting between rebels belonging to the Kurdistan Workers' Party, or PKK, and government forces flared up again in July, killing hundreds of people and derailing a fragile peace process with the Kurds.
