The United Nations is appealing for $74 million to aid flood victims in the Philippines.

U.N. spokeswoman Elisabeth Byrs says the money is needed to help 1 million people severely affected by the flooding resulting from Tropical Storm Ketsana.

The appeal to donors was issued Tuesday in Geneva and corresponds with the Philippines assessment of its needs for further assistance.

The September storm caused the worst flooding in Manila in more than four decades and killed more than 300 people overall.

The Philippines says it has received more than $13 million in funds and aid from at least 12 countries but needs more for feeding homeless people and rebuilding destroyed houses.
