ANKARA, Turkey (AP) — A 7.8 magnitude earthquake shook southeast Turkey early Monday and was felt in several provinces and elsewhere in the Middle East. The quake knocked down a number of buildings, reports said.

The U.S. Geological Survey said quake was centered about 20 miles from Gaziantep, a major city and provincial capital. It was about 16 miles from the town of Nurdagi.

It was centered 11 miles deep, according to the U.S. Geological Survey. A strong 6.7 aftershock rumbled about 10 minutes later.

Turkey’s Disaster and Emergency Management agency, AFAD, said the quake measured 7.4 and was centered in the town of Pazarcik, in Kahramanmaras province.

Several buildings tumbled down in the neighboring provinces of Malatya, Diyarbakir and Malatya, HaberTurk television reported. There was no immediate reports on casualties.

The earthquake was also felt in Lebanon and Syria.

Syria’s state media reported that some buildings collapsed in the northern city of Aleppo and the central city of Hama.

In Syria’s rebel-held northwest that borders Turkey several buildings collapsed, according to the opposition’s Syrian civil Defense.

In Damascus, buildings shook and many people went down to the streets in fear.

The quake jolted residents in Lebanon from beds, shaking buildings for about 40 seconds. Many residents of Beirut left their homes and took to the streets or drove in their cars away from buildings.

There were no immediate reports of major damage or casualties in either country.

Turkey sits on top of major fault lines and is frequently shaken by earthquakes.

Some 18,000 were killed in powerful earthquakes that hit northwest Turkey in 1999.
