Rescuers have pulled out a man alive from the rubble of a collapsed building four days after a powerful earthquake hit eastern Turkey, killing 532 people.

Television footage showed the man, surrounded by medics and other emergency workers, being rushed through hospital doors.

Rain and snow in the area is making life miserable for thousands of earthquake survivors.

Emergency officials said 2,300 people were injured and 185 have been rescued from the rubble after Sunday’s devastating 7.2-magnitude quake.

Television footage showed a rescue team cheering and clapping as the man, wearing a red sweater and strapped to a stretcher, was carried out of the debris. His eyes were shut most of the time, but he opened them at one point. He could not move his head, which was held steady in a brace.

“God is great,” someone sh-outed.

The man, identified as 18-year-old Imdat Padak, was rescued by an Azerbaijani crew.

He was flown to the nearby city of Van and was dehydrated, but in good condition. Mr Padak lives in the village of Kiziloren and was attending university preparation courses in Ercis, which was hardest hit by the quake.

More aid began to reach survivors, with Turkish authorities delivering more tents after acknowledging distribution problems that included aid trucks being looted even before they reached Ercis.

Families who did receive precious aid tents shared them with others. But some people spent a fourth night outdoors huddled under blankets in front of campfires, either waiting for news of the missing or keeping watch over damaged homes.

As survivors gathered pieces of wood to light campfires or stove-heaters, The Red Crescent and several pro-Islamic groups set up kitchens and dished out soup or rice and beans.

Looking ahead, Turkey’s we-ather agency predicted intermittent snowfall for the next three days.

Foreign assistance also began arriving. Israel, which has a troubled political relationship with Turkey, sent emergency housing units, blankets and clothing.
