The UN World Food Programme said Saturday that due to a lack of donations it was going to have to gradually stop supplying rations to 6.5 million North Koreans, and called on Pyongyang to lift restrictions on the distribution of aid. "We're doing our best to mobilize support, but we need more help from the authorities in Pyongyang," WFP Asia director Tony Banbury said in Beijing, following a four-day visit to North Korea. Because its stocks are exhausted, the WFP has already stopped providing vegetable oil to 900,000 old people, and as of this week will have to stop delivering essential nutritional supplements to 600,000 children in creches and nursery schools, Banbury said during a press conference. If nothing was done by the start of May, 1.2 million child and woman would not receive any more "WFP pulses" and a million other people would be deprived of cereals as of June, he said.
