More than 5,000 people are dead after a 7.8 magnitude earthquake rocked southeastern Turkey and northwestern Syria early Monday, according to officials. 

The pre-dawn quake was centered in the town of Pazarcik in Turkey's southeastern Kahramanmaras province and was followed by several powerful aftershocks. Thousands of buildings were toppled on both sides of the border, and the death toll was expected to rise as rescue workers searched for survivors in the massive piles of rubble. 

More than 8,000 people have been rescued in southeastern Turkey since a powerful earthquake and aftershocks struck the region, Turkish Vice President Fuat Oktay said at a press conference on Tuesday.

Some 24,000 first responders are on the ground, including more than 3,200 first responders from 14 other countries who traveled to Turkey to assist with the massive search and rescue effort following Monday’s quake. They are carefully combing through the wreckage and looking for survivors amid the 6,000 buildings that have been either damaged or destroyed, according to Oktay.
