A driver working for the World Food Programme was killed in an attack on Saturday in Sudan.
The contracted trucks were carrying WFP food commodities and were travelling between the cities of Dilling and Kadugli.
The attack came just one day after a WFP truck hit an explosive device in Dilling after delivering food assistance.
According to the UN, the trucks in question were clearly marked as humanitarian vehicles, the UN agency said in a statement.
As details of the circumstances of the incident are being investigated, the WFP is calling for an impartial probe with a view to holding those responsible accountable.
‘Security environment challenging’
According to the WFP statement the latest 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.
The Sudanese Armed Forces (SAF) and former allies the Rapid Support Forces (RSF) have been locked in a bitter struggle for power since April 2023.
Last year, more than 30 million people needed humanitarian assistance, according to the UN aid coordination office OCHA.
WFP urged all those involved in the fighting to respect their obligations under international humanitarian law, protect civilians and civilian infrastructure, and ensure safe and unimpeded access for both humanitarian personnel and cargo.
