At least 32 people were feared dead Monday when a powerful magnitude 7.8 earthquake struck off the southern Philippine island of Mindanao, prompting tsunami warnings in several countries.
National disaster authorities said at least a dozen people were still missing, while 134 had sustained injuries.
Philippine authorities urged people in affected coastal regions to move to higher ground after the offshore quake hit south of General Santos, a city of about 720,000, where at least nine were killed.
A series of powerful aftershocks rocked the area from about two hours after the first quake, according to the U.S. Geological Survey, with the largest measuring 6.5 magnitude.
In General Santos, an AFP journalist watched Monday afternoon as rescue workers dug through the rubble of a popular grocery store chain in a desperate bid to reach the bodies of two employees buried beneath.
