Malnutrition and diseases are increasing in North Korea as it faces a harvest that is half of what was expected that could lead to a food crisis in the country.
North Korea is under strict international sanctions over leader Kim Jong Un’s pursuit of nuclear weapons and ballistic missiles.
Drought had hit the North Korean economy which already faces difficulties such as widening trade deficits and foreign currency shortages.
International aid agencies have warned drought and floods.
Rainfall in North Korea has fallen by more than 30% this year deteriorating food situation as erratic weather will cause a lack of access to resources.
South Korea said it would donate $4.5 million to the UN World Food Programme (WFP) and also provide 50,000 tonnes of rice to its northern neighbour.
North Korea said measures to mitigate the effects of drought are being taken by digging canals and wells, installing pumps and transporting water.
