A powerful earthquake has hit a wide area in south-eastern Turkey, near the Syrian border, killing more than 100 people and trapping many others.

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.

In Turkey, officials confirmed more than 76 deaths so far and 10 cities hit, including Diyarbakir.

In Syria, more than 50 people were killed, state media reported.

There are fears the death toll will rise sharply in the coming hours.

Many buildings have collapsed and rescue teams have been deployed to search for survivors under huge piles of rubble.

Turkish Interior Minister Suleymon Soylu said 10 cities were affected: Gaziantep, Kahramanmaras, Hatay, Osmaniye, Adiyaman, Malatya, Sanliurfa, Adana, Diyarbakir and Kilis.

In Malatya province, north-east of Gaziantep, at least 23 people were killed, local officials said. In Sanliurfa, to the east, there were 17 deaths. And more deaths were reported in Diyarbakir and Osmaniye.

A BBC Turkish correspondent in Diyarbakir, reported that a shopping mall in the city collapsed.

The tremor was also felt in 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.

Rushdi Abualouf, a BBC producer in the Gaza Strip, said there was about 45 seconds of shaking in the house he was staying in.

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.

In a related development, at least 100 people have been killed and hundreds injured in Syria after a series of powerful earthquakes centered in southeastern Türkiye jolted the wider region early on Monday.

Strong tremors hit Idlib, Aleppo, Hama, Latakia, and Raqqa regions of Syria, the state-run SANA news agency reported.

At least 42 people have died and over 200 others are wounded in areas of Aleppo under the Bashar al-Assad regime’s control, the report said.

Dozens of buildings were also destroyed or damaged in opposition-held areas in northern Syria, where rescue teams are frantically searching for survivors.

In various areas in northern Syria, at least 58 people have been killed and hundreds injured, according to information compiled by Anadolu from several local sources, including the Syrian Human Rights Network and hospitals. (Based on reports by BBC and Anadolu Agency)
