Some 85,000 children under the age of five may have died from severe hunger in Yemen since the military intervention of the Saudi-led coalition began in 2015, Save the Children said.
FAO estimates that conservative estimates based on United Nations data suggest that 84.7 thousand children are severely malnourished, who may have died between April 2015 and October 2018.
"We are appalled that some 85,000 children in Yemen may have died because of the consequences of severe hunger since the start of the war," she said in a statement on Wednesday. "For every child killed by bombs and bullets, dozens of others die from hunger and disease, all of which can be prevented," she said.
According to the latest available statistics (due to 2016) by the United Nations for the number of war dead, more than ten thousand people have died.
Save the Children said more Yemeni lives were at risk of food insecurity due to the country's blockade and fighting around the port of Hodeidah in western Yemen.
The statement coincided with the arrival of UN envoy Martin Griffith to Sanaa on Wednesday to discuss with leaders of the Houthi group talks in Sweden next month to agree on a framework for peace under a transitional government.
The Saudi-UAE alliance last week ordered a halt to military operations in Hodeidah, the lifeline of millions of Yemenis. A few days later, the Huthis announced a halt to rocket and aircraft attacks on Saudi Arabia and the United Arab Emirates and coalition-backed Yemeni forces.
However, Hodeidah has seen heavy fighting over the past two days, mostly at night, with each trying to reinforce its positions.
