DAVAO CITY, Philippines, Jan. 13 -- At least 13 people are confirmed dead due to landslides and massive flooding in a number of areas in southern Philippines on Sunday, local government officials said Monday.

Loreto Rirao, civil defense chief for Davao region, said 11 of the fatalities were caused by landslides that hit mining communities in Compostela Valley and Davao Oriental provinces.

Rirao said two people were drowned after floodwater swamped communities in Bayugan City in Agusan del Sur province.

The landslides and floods injured 10 others while 14 people were reported missing.

The flooding and landslides spawned by days of continuous rains due to a lingering low pressure area also displaced some 12,000 people in southern Philippines.

In Compostela Valley province alone, provincial police chief Senior Supt. Camilo Cascolan said some 1,200 families or about 1, 500 individuals have been evacuated.

Several bridges and homes were also destroyed or washed out and major roads were submerged in floodwater.
