Sudanese authorities have announced that they are immediately restricting the movement of humanitarian workers operating in the south of the region because of ongoing military operations -the United Nations reported today.

The announcement comes two days after Sudanese armed forces launched air strikes against the South Darfur town of Labado and the village of Esheraya.

Aid workers also face restrictions at Kalma camp, home to at least 90,000 people. More than 130,000 people are in Guerida camp which is also in South Darfur.
