More than 15,000 people have been killed and tens of thousands injured after a magnitude 7.8 earthquake struck Turkey and Syria on Monday, according to officials.
At least three US citizens were killed in Turkey, the State Department said.Thousands of buildings collapsed and aid agencies are particularly worried about northwestern Syria, where more than 4 million people were already relying on humanitarian assistance.Freezing weather conditions are further endangering survivors and complicating rescue efforts, as more than 100 aftershocks have struck the region.
