Juba, South Sudan: The World Food Programme suspended work in parts of northern South Sudan after a river convoy carrying 1,500 tonnes of aid was attacked and looted, it said Wednesday.
There has been rising violence in recent weeks mostly centred on Jonglei state where at least 280,000 people have been displaced, according to a United Nations report on Tuesday.
WFP said it came under attack last week in neighbouring Upper Nile state, another region considered a stronghold of Machar's forces.
"A 12-boat WFP convoy transporting over 1,500 metric tons of vital food assistance was attacked multiple times by armed youth," it said in a statement.
The cargo, which also included non-food items from partners, was looted overnight "without security intervention" from local authorities, WFP said, despite their safety assurances.
"WFP has suspended all activities in Baliet County until the safety and security of its staff, partners and contractors is assured," it said, and until the government recovers the stolen items.
"Attacks on humanitarians are never acceptable," WFP added.
Last week WFP and Doctors Without Borders (MSF) denounced restrictions on humanitarian access to Jonglei, with MSF also forced to evacuate one of its health facilities due to armed clashes.
