About 16 UN aid workers have been kidnapped in the troubled Sudanese region of Darfur, the state minister for foreign affairs has said.
Nejib al-Khari Abdel Wahab said contact had been made with their abductors and negotiations were under way.
There has been no confirmation by the UN, which was beginning an operation to try to avert a humanitarian crisis.
About 10,000 people have died, and a million made homeless, in a conflict between rebels and Arab militias.
