Battling near-freezing temperatures and darkness, rescue workers and residents in eastern Turkey early Monday scoured the wreckage wrought by the country's most-powerful earthquake in more than a decade, hoping to find survivors.
They used flashlights, shovels, heavy machinery and their hands to lift the debris, and climbed over collapsed buildings in search of victims.
At least 217 people were killed in Sunday's quake, said Turkish Interior Minister Idris Naim Sahin, the Anatolian news agency reported Monday. The previous official toll was 138.
Another 350 people were injured in the quake, which the U.S. Geological Survey said had a magnitude of 7.2.
Roughly 20 aftershocks rattled eastern Turkey in one of the nation's poorest areas. The largest had a magnitude of 6.0.
One hundred people were killed in Van, while 117 were killed in Ercis, said Sahin, the Anatolian news agency reported. It also said that schools will be closed for a week in Van.
Turkish Prime Minister Recep Tayyip Erdogan told reporters the death toll is likely to climb, as rescue teams work through the night to save people are still trapped in the rubble.
The prime minister said 55 buildings collapsed in Ercis on the north shore of Lake Van, while the Turkish Red Crescent had said earlier that some 25 apartment buildings and a student dormitory collapsed in the town.
Local rescuers took many wounded people out of the dormitory, a Red Crescent statement said, without saying exactly how many.
A health services building also collapsed, along with part of a hospital, CNN sister network CNN Turk reported. The injured were being treated in the hospital's garden.
"People are really scared," said CNN Turk reporter Nevsin Mengu. "The survivors are now trying to survive the cold weather."
She said many residents are not returning to their houses, but sleeping on rooftops or in the streets. It was not clear whether their homes were uninhabitable, or whether they were just too frightened. Electricity and natural gas were off in most of the city.
Speaking from Van, Mengu said the death toll is almost sure to rise, as rescue teams have not yet reached some of the smaller villages. Trucks carrying medical aid and food were seen driving into Van.
Official rescue efforts were also underway in Ercis, said CNN Turk reporter Sevda Incesu, but residents were conducting efforts of their own. Ambulances were having trouble getting into town because the roads were littered with debris, she said.
Video footage from the scene showed survivors freed from the rubble being loaded onto stretchers amid a crush of rescue workers and bystanders. Heavy equipment was used to sift through the wreckage, as residents gathered around small fires.
The Red Crescent called for rescue workers, machinery and drinking water. A crisis centre was set up by the country's Health Ministry in the Turkish capital, Ankara.
Health Minister Recep Akdag said an air ambulance and several helicopters would go to the quake zone.
Rescue teams of about 500 people were on the ground, according to the crisis centre, and additional aid teams were dispatched from 29 surrounding cities. Medical helicopters were transporting the injured to hospitals in other provinces, the centre said.
Two tent hospitals were being set up in Ercis, and two cargo planes were dispatched from the capital carrying medical teams and aid.
A seven-story building collapsed on Kazim Karabekir Street in the city of Van, and more buildings were reduced to rubble the village of Tabanli in Van province, the Anatolian news agency said. It was unknown how many people were trapped.
Prime Minister Erdogan and Health Minister Akdag arrived in the area Sunday, according to the Ministry of Health's crisis center.
Israel offered Turkey "any help it may require" after the earthquake, Defence Minister Ehud Barak's office said. Israel and Turkey, once close allies, saw deterioration in relations in a dispute over an Israeli naval commando raid on the Gaza-bound ship Mavi Marmara, in which nine Turkish activists were killed.
Other nations and organisations offered condolences and assistance to Turkey.
"Our thoughts and prayers are with the brave men and women who are working to bring assistance to this stricken region," U.S. President Barack Obama said in a statement. "We stand shoulder to shoulder with our Turkish ally at this difficult time, and are ready to assist the Turkish authorities." U.S. Secretary of State Hillary Clinton issued a similar statement.
A spokesman for the Turkish Foreign Ministry said the country, while grateful for offers of aid, is prepared to handle the disaster on its own.
Turkey is "no stranger to having these seismic events," but Sunday's quake is considered major, CNN Meteorologist Reynolds Wolf reported.
A magnitude 7.6 earthquake in Izmit, Turkey, killed more than 17,000 people in 1999, according to the USGS. A magnitude 7.2 tremor in Duzce the same year killed 894 people, the USGS reported.
Sunday's major quake hit at 1:41 p.m. local time.
It took place about 12 miles from Van, the USGS said.
The USGS reported a depth of 4.5 miles, or 7.2 kilometers; the center in Turkey said the quake was about three miles, or five kilometres, deep. (Source: CNN)
