- Also felt in neighboring countries, particularly in Lebanon, Cyprus, Syria and Jordan
A powerful earthquake has hit Gaziantep in south-eastern Turkey, near the border with Syria, killing at least 17 people.
The US Geological Survey said the 7.8 magnitude tremor struck at 04:17 local time (01:17 GMT) at a depth of 17.9km (11 miles) near the city of Gaziantep.
The quake was felt in the capital Ankara and other Turkish cities, and also across the wider region.
Many buildings have collapsed, and there are reports of people trapped.
Local Turkish officials say at least 17 people have died – but the death toll has been rising steadily.
Turkish Interior Minister Suleymon Soylu said 10 cities were affected: Gaziantep, Kahramanmaras, Hatay, Osmaniye, Adiyaman, Malatya, Sanliurfa, Adana, Diyarbakir and Kilis.
A BBC Turkish correspondent in Diyarbakir, north-east of Gaziantep, reported that a shopping mall in the city collapsed.
The tremor was also felt in Syria, Lebanon and Cyprus.
“I was writing something and just all of a sudden the entire building started shaking and yes I didn’t really know what to feel,” Mohamad El Chamaa, a student in the Lebanese capital Beirut, told the BBC.
“I was right next to the window so I was just scared that they might shatter. It went on for four-five minutes and it was pretty horrific. It was mind-blowing,” he said.
Turkish seismologists estimated the strength of the quake to be 7.4 magnitude.
They said that a second tremor hit the region just minutes later.
Turkey lies in one of the world’s most active earthquake zones.
