The head of the UN food agency has appealed for aid to avert a humanitarian crisis in the conflict-wracked DR Congo province of Kasai.
David Beasley told the BBC that more than three million people were now at risk of starvation.
He warned that hundreds of thousands of children could die in the coming months if aid was not delivered.
Violence flared in August 2016 after the death of a local leader during clashes with security forces.
It has forced 1.5 million million people from their homes, most of them children
Mr Beasley described the situation in Kasai as a “disaster”.
“Our teams are out in the field, we saw burned huts, burned homes, seriously malnourished children that had been stunted, obviously many children have died already,” the head of the World Food programme (WFP) said.
“We’re talking about several hundred thousand children there that will die in the next few months, if we don’t get first funds and then second food, and then third access in the right locations,” he added.
He said the WFP currently only had 1% of the funding it needed to help people in Kasai and warned that the coming rainy season would soon make already poor roads impassable.
But delivering aid by air would see costs escalate, he said.
“If we wait another few more weeks before we receive funds, to pre-position food, I can’t imagine how horrible the situation is going to be,” he said.
“We need help, and we need it right now,” he added.
