Many people have been left with nothing but what they are wearing
Rescue workers are being overwhelmed by the scale of floods in the Philippines that are estimated to have killed at least 140 people, officials say.
The head of the National Disaster Co-ordinating Council, Anthony Golez, said resources were being spread too thinly.
Torrential rains from Tropical Storm Ketsana flooded the capital, Manila, and 25 nearby provinces on Saturday.
Some 80% of Manila was submerged, displacing 450,000 people. More than 115,000 are now in makeshift shelters.
"We are concentrating on massive relief operations. The system is overwhelmed, local government units are overwhelmed," Mr Golez told reporters.
