"An estimated 967,000 children under five are suffering from acute malnutrition," United Nations spokesman Martin Nesirky said at a press briefing on Wednesday, Xinhua reported.
Meanwhile, the world body has appealed to the international community to assist millions of vulnerable people in Yemen who are in need of healthcare, clean water, basic sanitation, and nutrition.
In response to the crisis, aid organizations in the impoverished Arab country are asking for nearly $40 million to help 267,000 children who are at risk of dying if proper treatment is not administered.
Children in Yemen also face the threat of unexploded ordnance and land mines, which have reportedly claimed the lives of 13 children and left another dozen injured in the first quarter of 2012.
