The International Federation of the Red Cross says its Turkish chapter is working to assist survivors and reach those trapped in the rubble. The Red Cross says more than 7,500 tents and 22,000 blankets have been distributed, as well as stoves, food and clean water.

Officials say the quake did the most damage in the town of Ercis, 90 kilometers north of the city of Van, shutting down electricity and water in several areas. Hundreds of aftershocks have shaken the area since the quake hit, including a moderately strong one on Tuesday, measuring 5.4, that sent people rushing into the streets.

World leaders have sent condolences to Turkey. Russian President Dmitry Medvedev and President Serzh Sarkisian of Armenia made a joint telephone call to Turkish President Abdullah Gul to express their sympathies. U.S. President Barack Obama said the United States will stand “shoulder to shoulder” with Turkey during this difficult time.

United Nations Secretary-General Ban Ki-moon praised Turkish authorities for their rapid response to the disaster and said the U.N. remains ready to offer help if requested.
