It is not yet clear how many people were crushed in their own homes in Turkey, a country infamous for its poor construction. Rescuers search the rubble for survivors and bodies.
Duygu Kati, principal of a high school, told CBS News that she had safely evacuated all of her students. She said the building almost collapsed.
Because it is positioned on a number of major fault lines, Turkey is one of the most earthquake-prone countries in the world, according to Reuters. More than 17,000 people have died as a result of earthquakes in the country in recent decades.

Turkey and Greece are currently fighting over exploration rights in the Mediterranean, Reuters reported – but the two leaders tweeted about the need for solidarity in times of crisis.
“Whatever our differences, these are times when our people must be united,” wrote Greek Prime Minister Kyriakos Mitsotakis. “It is more precious than much in life that two neighbors show solidarity in difficult times,” Turkish President Tayyip Erdogan said.
