Rescue teams continued working into the night in the hunt for 32 children still trapped under a Turkish boarding school dormitory that collapsed in an earthquake.
But most had given up hope of recovering any more youngsters alive from the ruins of the building in Celtiksuyu.
No signs of life emerged from under the debris of the four storey building and rescuers began using cranes and heavy equipment to work through the debris despite protests of the parents of those still missing.
"God took him, why are you cutting him into pieces?" screamed Mr Fethi Ketenalp, the father of a 14-year-old still trapped under the rubble, throwing himself in front of a crane.
Although sniffer dogs and electronic listening equipment had not located any survivors since morning, rescue workers insisted that they still harboured hope. People can live for several days trapped under debris.
"This is still a search and rescue operation," insisted Mr Ahmet Aydin, in charge of the emergency centre at the site.
By evening, 32 pupils were still missing after 117 had been rescued and 49 found dead, rescue officials said. The children, aged seven to 16, were mostly sons of poor Kurdish farmers.
Many parents vented their anger at the quality of the school's building. Public Works and Housing Minister Mr Zeki Ergezen said an investigation had been launched against the contractor of the school.
"Murderers," shouted Ms Gazal Gunalan, whose 15-year-old son Mehmet was buried under the rubble. "Look at this building, it is the bad construction that took the lives of our children."
Ms Gunalan said she had lost all hope. No one had been found alive since 10 a.m. today.
The confirmed death toll from Thursday's quake rose to 115 said officials. About 1,000 people were injured.
Thousands were left homeless and anger over the lack of tents, food and water erupted into violent clashes in the city of Bingol, the predominantly Kurdish city hit by Thursday's 6.4 magnitude quake.
Police fired shots into the air with automatic rifles to disperse demonstrators demanding the resignation of Bingol Governor Huseyin Avni Cos and throwing stones at the building. Some protesters threw themselves on the ground.
Anger grew after a police van injured several demonstrators by speeding through the crowd. Clashes spread to side streets with young Kurds tearing large stones from the paved streets to throw them on police cars and armoured vehicles. Policemen wearing balaclavas could be seen running down streets firing their automatic weapons into the air.
At least five policemen and three journalists were injured and several were detained, the governor said.
