Almost 1,500 people are now known to have died in flash floods that struck the southern Philippines more than a week ago. Officials said that more bodies had been found in the waters south of the island of Mindanao, the (BBC) reported Tuesday. It is not clear how many people are still missing but officials said the search for bodies will continue. Typhoon Washi struck from 16 to 18 December, devastating the cities of Cagayan de Oro and Iligan. Many of those who died were sleeping as Typhoon Washi caused rivers to burst their banks, leading to landslides. Entire villages were washed away. The civil defence office said the number of people now known to have died had risen to 1,453 after 200 more bodies were found in the water. The regional civil defence chief Ana Caneda said that they expected to find more. "There are still a lot of areas we have examined that are stinking of dead bodies," she told the agency. "We don''t know how many people are buried under that mud." The national disaster agency said it could take up to six months to build temporary housing for the 60,000 who are now homeless in the wake of the storm. Many of them are currently taking temporary shelter in school buildings. Aid agencies have appealed for funds to help those who are affected. The United Nations is seeking $28.6m (?18.2m) from donors to help provide water and sanitation to storm victims.
