MANILA, Philippines (AP) – Officials say flashfloods and landslides have killed at least 12 people in the southern Philippines.

Heavy rains and strong winds triggered by Typhoon Fengshen caused widespread damage, officials said.

A swollen river overflowed its banks and swept away three houses in a riverside village in South Upi township in southern Maguindanao province, drowning 10 people, provincial administrator Norie Unas said. Five others were missing.

In nearby Cotabato city, a 50-year-old man and his 10-year-old grandson were killed when a landslide buried their home in a hillside shanty community, Mayor Muslimin Sema said.

The National Disaster Coordinating Council reported flooding and power outages caused by toppled power pylons in many areas in the central Philippines.
