Rescuers are desperately searching for survivors in southern Turkey and northern Syria after two huge earthquakes on Monday.

More than 7,800 people have been killed, but there are warnings the death toll could continue to surge.

As search efforts continue into a second freezing-cold night, time is running out for rescuers to find survivors under the rubble.

The first 7.8 magnitude quake struck near Gaziantep in the early hours of Monday, followed by a 7.5 magnitude tremor hours later
