The UN’s top aid official has warned that the “will to end the fight still was not there” after speaking to Sudan’s rival military leaders.
Martin Griffiths told the BBC that Sudan’s descent into violence was now at a dangerous tipping point.
He called for security guarantees from the warring sides to allow humanitarian aid into the country.
The UN warns that the fighting could force hundreds of thousands of Sudanese to flee their homes.
In a BBC interview hours after his visit to Port Sudan, Mr Griffiths spoke bluntly of what he called “the rigid existential fact that those at war are keen to keep it going”.
During his time in Sudan’s largest port, now a major evacuation and humanitarian hub, he had separate telephone conversations with Sudan’s rival generals.
