The world's largest disaster relief network said in a statement issued in Geneva that the international sanctions imposed on North Korea over its missile and nuclear programs had exacerbated the worrying situation.

Iranpress/Asia : IFRC announced, North Korea has not seen a drop of rain since early July as temperatures soared to an average 39 degrees Celsius (102 Fahrenheit) across the country. The next rainfall was expected in mid-August.

The population of 25 million is already stressed and vulnerable with malnutrition among children that could worsen, the network said in a statement issued in Geneva.

About 70% of North Koreans are "food insecure", meaning they struggle to avoid hunger, and one in four children under five is stunted from chronic malnutrition, the WFP said at the time.

A famine hit North Korea in the mid-1990s and killed up to three million people.

Back in May, the UN's World Food Programme (WFP) said around 70 percent of North Koreans are "food insecure," meaning constantly struggling against hunger, adding that one out of every four kids under five is stunted from chronic malnutrition.
