A United Nations official says 12 nations have offered or begun sending relief aid to flood-stricken North Korea.

Special envoy for relief aid Margarita Walstrom said Sunday that U.N. member nations including South Korea, Japan, the United States, Russia, Italy and Finland, have pledged financial aid or began sending assistance to the North.

She said the World Food Program has completed two days of field research with North Korean officials, and other U.N. agencies are also preparing to send relief aid.

The program has prepared 4-thousand tons of food aid, enough to feed 320-thousand people.

The World Health Organization will send emergency medical supplies for about 80-thousand people, and the U.N. Population Fund will ship supplies for households.
