Darfur aid 'on brink of collapse'

Fourteen UN aid agencies working in Sudan's troubled Darfur region have warned that their relief operations will collapse unless security improves.

Humanitarian workers, they said, are 'holding the line' for the survival and protection of millions in Darfur. But they need 'solid guarantees' of security from all the parties involved in the conflict to be able to continue.

Violence in the western region of Sudan has claimed more than 200,000 lives and led 2.5 million to abandon their homes.
