It was one of the most powerful earthquakes ever recorded in Turkey, even shaking buildings hundreds of miles away in Israel.
Most of the initial casualties from the magnitude 7.8 temblor that hit early Monday were in Turkey and neighboring Syria. The two countries have reported a total of over 1,000 deaths, but the toll was expected to increase.
