Rescuers on Monday raced to reach several people believed trapped inside a supermarket that crumbled as a magnitude-6.9 quake violently shook the southern Philippines this weekend, killing at least five people, officials said.

At least two people were killed when the store collapsed at the Southern Trade shopping center in the town of Padada, an impoverished community in the province of Davao del Sur, which bore the brunt of the temblor.

“Rescuers were able to pull out two female bodies from the rubble” before dawn, said Francisco Guerrero, the vice mayor of Padada.

On Sunday, a 6-year-old girl was killed after a wall collapsed on her at a separate location. The government also reported two other people dying of heart attacks related to the quake.
