A shallow magnitude 6.4 earthquake struck the Turkey-Syria border region after it was devastated earlier this month by temblors that killed tens of thousands of people.
Monday’s aftershock in Turkey’s Hatay province was at a depth of 2km (1.2 miles), the European Mediterranean Seismological Centre said.
The quake hit the town of Defne at 8:04pm (17:04 GMT) and was strongly felt in the cities of Antakya and Adana, 200km (300 miles) to the north.
A second magnitude 5.8 centred in Samandag district of Hatay shook the region several minutes later, Turkey’s emergency management agency said.
There were no immediate reports of casualties. Turkey’s state-run Anadolu news agency said the temblors were felt in Syria, Jordan, Israel and Egypt.
