Turkish authorities say the death toll from the earthquakes centred in southeastern Turkey rose to 3,419, bringing the total number of killed, including those in northern Syria, to more than 5,000.
The initial magnitude 7.8 tremor early on Monday brought down buildings as people slept and was followed by a magnitude 7.6 earthquake hours later amid several aftershocks.
The United States Geological Survey said the initial earthquake was centred about 33km (20 miles) from Gaziantep, a major Turkish city and provincial capital.
