Celtiksuyu, Turkey ? Listening for young voices, rescuers early today searched for dozens of children buried in the rubble of their dormitory after an earthquake struck southeastern Turkey. At least 100 people were killed and 1,000 injured.

Search teams working all day Thursday and into the early hours today were in contact with four of the children, state-owned TRT television reported from the scene. But there were few signs of 80 other children trapped in the collapsed four-story building.

Some parents were giving up hope. Cevriye Bartir, mother of missing 15-year-old Sinan, sat on the step of a fire truck wailing, “My dead son, let me be sacrificed instead.”

The 198 students in the dorm, ages 7 to 16, were asleep when the tremor hit early Thursday morning and collapsed the building. At least 21 were killed, along with a teacher. But 93 others were pulled out alive.

Steel bunk beds and steel closets helped hold up some of the walls of the school, saving many lives, rescuers said.

Soldiers, rescuers and ordinary citizens lifted huge concrete slabs with cranes and jackhammers in a search for survivors. Some just used their bare hands.

Every now and then, noisy equipment was turned off to allow rescuers to listen for voices. Dogs also sniffed for survivors.

The quake was centered just outside Bingol, a city of 250,000 in a largely rural area mostly inhabited by Kurds. The school was intended for the children of poor farmers from villages that have no schools.

Crews work to rescue a man from under the debris of a damaged building in Bingol, Turkey. A strong earthquake killed at least 100 people early Thursday in southeastern Turkey and wreaked havoc on many of the cities' structures.

Relatives rushed toward soldiers every time a rescued child was carried out on a stretcher.

“Oh my God! Oh my God! My son is lost, he is lost, he is lost! I cannot take the pain any more!” cried out Sefika Celik, whose 14-year-old son Alican was trapped in the debris.

Many students were being treated for their injuries on mattresses laid out near the flattened building. Naim Gencgul, a 15-year-old boy, was pulled out of the rubble with a broken arm.

“The whole building was on top of me. We all started screaming,” he said.

In Bingol, a bridge and at least 25 buildings collapsed, Mayor Feyzullah Karaaslan said. Damage could be seen throughout the city, where the streets were filled with terrified residents.
