MANILA, Philippines: Two days of heavy rains set off floods and landslides in the southeastern Philippines, leaving at least 20 people dead, 13 missing and thousands displaced, officials said Monday.

Most of the dead and missing came from floods and landslides that hit Compostella Valley and Davao Oriental provinces, said Maj. Reynaldo Balido, spokesman for the disaster-response agency.

A landslide Monday damaged five houses in Cagdianao municipality in Dinagat Island, off the northeastern coast of the main southern island of Mindanao, killing six residents including two boys aged 2 and 14, said police officer Elbert Ompoc.

Another man drowned in Agusan del Sur province’s Prosperidad township, on Mindanao, and seven others were missing, according to the civil defense regional bureau.

The flooding, triggered by rains from a low pressure area, has affected 132,000 people from 10 provinces.

Liza Mazo, a regional disaster-response official, said some 10,000 people fled to safer grounds in four provinces and an island.

The same area was hit by a typhoon in December 2012, leaving nearly 2,000 people dead and missing and causing massive destruction.

Government weather forecaster Gener Quitlong said rains may persist until Tuesday or Wednesday over central provinces, including those hit by Typhoon Haiyan, which killed more than 6,100 people and left nearly 1,800 others missing on Nov. 8.

24 wounded

in school blast

In Cotabato, a suspected improvised bomb attack at a university campus in the Philippines, has left 24 people wounded — many critically — including students and teachers, police said Monday.

It appeared a fire was set off deliberately in a school building housing security personnel at the state-run Cotabato Foundation College of Science and Technology, before the blast occurred Sunday night, police added.

“The fire drew responders, including firemen, teachers, and students, and they were among the injured,” explained Senior Inspector Rolly Oranza of the local police force in the troubled Mindanao region.

He said 17 of the wounded remain in a critical condition at the hospital.

Police told AFP they believe the explosion was caused by an improvised explosive device, but ordnance experts are still determining the exact details.

No group has claimed responsibility for the attack, and police are still trying to determine the motive, Inspector Oranza said.

The school is situated in Arakan, a quiet farming community on the southern island of Mindanao, populated mostly by indigenous tribes.
