Philippines – 12,000 Displaced by Floods in Zamboanga

Heavy rain, strong winds and storm surge have caused flooding in areas around Zamboanga, Mindanao, Philippines.

Zamboanga City mayor, Beng Climaco, said that at least one person has died. Over 12,000 people (2,448 families) from 12 barangays (municipalities) have been displaced and are currently staying in local public buildings.
