Five people were injured when a pipe bomb exploded on an overpass near an Istanbul metro station on Tuesday, the district mayor told A Haber television.
Atilla Aydiner, the mayor of the Bayrampasa district on the European side of the city, spoke on live television after the explosion hit the industrial and residential area near the height of evening rush hour.
Initial reports said that least one person was killed in the incident, and the explosion was first believed to have been from a power transformer, Turkey’s Haberturk reported.
A municipal official told Reuters that train operations had been suspended at the Bayrampasa metro station after a loud noise was heard. The Associated Press reported that subway services throughout Istanbul had been halted on the entire network.
The state-run Anadolu Agency, meanwhile, said the explosion occurred at an overpass near the station, not in the station itself. Although Istanbul’s metro is largely underground, it runs above ground in some places, including around Bayrampasa.
