The contracted vehicles were travelling between Dilling and Kadugli early on Saturday when the attack occurred.
The WFP said the trucks were clearly identifiable as humanitarian vehicles and were transporting food commodities for communities dependent on emergency assistance.
The circumstances surrounding the attack and the extent of the damage to the food supplies were still being established.
WFP strongly condemned the strike and called for a prompt, impartial investigation.
The United Nations (UN) agency said those responsible must be identified and held accountable.
The attack occurred one day after another WFP truck struck an explosive device in Dilling after delivering food assistance. “These incidents underscore the increasingly challenging security environment in Sudan and the risks that aid workers face when delivering life-saving assistance to communities in need,” WFP said.
The incidents threaten humanitarian operations in a country where conflict has left millions of people reliant on emergency food, healthcare, shelter and other essential support.
The Sudanese Armed Forces and Rapid Support Forces have been fighting since April 2023.
More than 30 million people required humanitarian assistance in 2025, according to the UN Office for the Coordination of Humanitarian Affairs.
WFP said the increasing danger facing humanitarian workers and vehicles was complicating efforts to reach vulnerable communities.
The organisation reaffirmed its commitment to providing food assistance to millions of people across Sudan despite the worsening security environment.
WFP called on all parties to the conflict to comply with international humanitarian law and protect civilians, humanitarian workers and civilian infrastructure.
The agency also demanded safe and unrestricted access for humanitarian personnel and cargo travelling to communities affected by the conflict.
Disruption to aid routes could delay assistance, damage essential supplies and leave already vulnerable families without lifesaving support.
WFP said humanitarian personnel must be allowed to carry out their work safely and without interference.
