I couldn't save my daughter, the defining image of the Turkey earthquake.

(cnn) ⸻ Mesut Hancer's photograph of his 15-year-old daughter, Irmak, under the rubble in the southern Turkish city of Kahramanmaras, near the epicenter of the quake, has become a symbol of the tragedy of the past week. Hancer spent three days trying to free her body from the rubble, but he was unable to save her. He said she died at the moment it hit, with no chance of escape. When Hancer arrived at the wreckage, the terrible reality of the situation became apparent. He didn't have hope because there was a large girder on her, and she was crushed. The death toll in Turkey has reached 31,643, and the confirmed death toll in Syria is 4,574. Rescue efforts continue in both countries, but authorities have been overwhelmed by the sheer scale of the disaster. Turkish authorities have carried out a wave of arrests of property developers accused of "negligence" over building collapses due to last week's earthquake. The earthquake struck when members of Hancer's family had traveled across Turkey to his mother's house, where his daughter was staying. Hancer spent three days trying to free his daughter's body from the rubble, and his home has been badly damaged. He doesn't have anywhere to stay, and thousands of families are facing similar grief and devastation.
