A magnitude 6 earthquake has reportedly hit the city of Düzce in the west of Turkey, 175 km east of Istanbul. The quake struck at 04:08am local time on Wednesday morning and was at a depth of 2 km (1.24 miles), according to the European-Mediterranean Seismological Centre (EMSC).
The independent scientific organisation officially issued a tsunami warning and urged residents to seek higher ground.
The EMSC tweeted: “Move away from the coast and reach a higher place. Follow national authorities’ directives.”
Posts on Twitter claimed that the earthquake had been felt in the capital Ankara and the country’s biggest city Istanbul, with users saying the buildings had “shook”.
