Pipe Bomb Explodes in Istanbul, Wounding 5 at Rush Hour

ISTANBUL — A pipe bomb left on a highway overpass near an Istanbul subway station exploded Tuesday, wounding five people, a local official said. The blast caused some panic in the city, which is on edge following a spate of deadly bombings in Turkey.

The bomb was left at the start of the evening rush hour near the Bayrampasa subway station on Istanbul's European side, said Atilla Aydiner, the mayor for Istanbul's Bayrampasa district, who said five people were hurt.

There was no immediate claim of responsibility.
