A pipe bomb explosion has rocked a metro station in Turkey’s strategic city of Istanbul, Turkish media say.
The blast took place on an overpass close to the Bayrampasa subway station, located on the European side of the city, the state-run Anadolu Agency reported.
There were conflicting reports on the number of casualties and the cause of the incident.
Atilla Aydiner, the mayor of Istabbul’s Bayrampasa district, noted that five people were wounded in Tuesday’s explosion which came during the evening rush hour.
Turkey’s Habertürk television said that one person had died.
