Yemen’s rebels, previously accused of diverting humanitarian aid in the war-torn country, claimed Friday that the World Food Program (WFP) lacked neutrality, after it won the Nobel Peace Prize for fighting global hunger.

Meanwhile, Yemen’s internationally recognized government welcomed the choice of winner, pointing to the “wise and courageous” leadership of the United Nation agency’s executive director, David Beasley. Iran-backed Houthi insurgents have been fighting for control of Yemen since 2014.

A Saudi-led military coalition intervened in support of the government the following year.

“We find that the WFP has largely failed in the biggest task for which it was chosen (for the Nobel Peace Prize), and that is combating hunger,” Talaat al-Sharjabi, a Houthi spokesman, told Agence France-Presse (AFP) shortly after the announcement.

“A large number of people suffer from malnutrition… and there is also a failure on the WFP’s part to be neutral in terms of humanitarian aid distribution,” he said.
