At least 19 dead after major earthquake strikes southern Philippines

At least 19 people have died after a magnitude-7.8 earthquake struck off the coast of Mindanao island in the southern Philippines, officials say.

The quake occurred on Monday at 07:37 local time (Sunday 23:37 GMT), triggering tsunami alerts in the Philippines, Indonesia, Japan and Australia. Some of those were cancelled hours later.

Videos and images showed buildings collapsing, including a clip of a Jollibee fast food restaurant reduced to rubble.

At least 134 people were reportedly injured across several provinces - South Cotabato, Sultan Kudarat, Sarangani - and the city of General Santos, a local official said. These numbers still need to be verified by the national disaster agency.

The official count from the agency - the National Disaster Risk Reduction and Management Council - typically comes about a day after the incident. They tabulate all the numbers given by various sources including the police, local officials and disaster relief agencies.

Philippine President Ferdinand Marcos Jr said in a statement that agencies were coordinating their disaster response.

"The national government is moving and we will not leave Mindanao behind," he promised.

Marcos also ordered the suspension of classes in affected areas after the quake, which coincided with the first day of the school year in the Philippines.
