The World Food Programme (WFP)has suspended food distribution in Ethiopia’s Kombolcha and Dessie towns after looting of supplies that staff were unable to stop due to intimidation, including being held at gunpoint, the United Nations said on Wednesday.

UN Spokesman Stephane Dujarric said a large quantity of humanitarian food supplies, including nutritional items formal nourished children, were stolen and looted in Kombolcha in the Amhara region.

“The small scale theft of food escalated into mass looting of warehouses across Kombolcha in recent days, reportedly by elements of the Tigrayan forces and some members of the local population,” Dujarric told reporters.

“Such harassment of humanitarian staff by armed forces is unacceptable. It undermines the ability of the United Nations and all of our humanitarian partners to deliver assistance when it is most needed,” he added.

The incidents will worsen malnutrition and prolong food insecurity in northern Ethiopia, where an estimated 9.4 million people across the Tigray, Amhara and Afar regions are now in need of critical food assistance, Dujarric said.

Three WFP trucks used for humanitarian operations in Amharawere commandeered by military personnel and used for their own purposes this week, Dujarric also said, condemning the incidents and calling for all parties to the conflict to respect and protect humanitarian relief personnel and objects.

The year-long war between the federal government and the leadership of the northern region of Tigray has killed thousands of civilians, forced millions to flee their homes, and made more than 9 million people dependent on food aid.

Ethiopian forces have Dessie and Kombolcha from rebellious Tigrayan forces, the government said on Monday, in the latest sign of the government retaking territory.
