UN humanitarian chief Martin Griffiths arrived in Jeddah, Saudi Arabia, on Sunday for talks aiming for a ceasefire between Sudan’s warring military factions, a spokesperson said.
Mr Griffiths is in Jeddah “to engage in humanitarian issues related to Sudan,” UN spokeswoman Eri Kaneko said.
Representatives from Sudan’s warring armies are in Saudi Arabia for their first face-to-face negotiations.
The “pre-negotiation talks” between the Sudanese army and the paramilitary Rapid Support Forces (RSF) started on Saturday in Jeddah. They are sponsored by the US and Saudi Arabia.
Several ceasefires have broken down since the fighting began weeks ago.
Hundreds of people have been killed and nearly 450,000 civilians displaced since the fighting began.
