Rescuers are battling heavy rain and snow as they race against the clock to find survivors of a devastating earthquake in south-east Turkey.
More than 4,300 people were killed in Turkey and over the border in Syria when the quake struck in the early hours of Monday.
The World Health Organisation has warned the toll may rise dramatically as rescuers find more victims.
Many people in the disaster zone are too scared to return to buildings.
The 7.8 magnitude tremor struck at 04:17 (01:17 GMT) on Monday at a depth of 17.9km (11 miles) near the city of Gaziantep, according to the US Geological Survey.
Seismologists say it was one of the largest ever recorded in Turkey, where at least 2,921 people are now known to have died.
Survivors say it took two minutes for the shaking to stop.
A later tremor had a magnitude of 7.5, and its epicentre was in the Elbistan district of Kahramanmaras province.
At least 1,400 people are now known to have been killed in Syria where millions of refugees live in camps on the Turkish border.
Following an international appeal for help, Turkey's President Recep Tayyip Erdogan said 45 countries had offered support.
UN Secretary General António Guterres called for an international response, saying that many of the families hit by the disaster were "already in dire need of humanitarian aid in areas where access is a challenge".
The European Union is sending search and rescue teams to Turkey, while rescuers from the Netherlands and Romania are already on their way.
The UK has said it will send 76 specialists, equipment and rescue dogs.
France, Germany, Israel, and the US have also pledged to help. Russian President Vladimir Putin has offered help to both Turkey and Syria, as has Iran.
