Nairobi  - Medical humanitarian organization Medecins Sans Frontieres (MSF) is to withdraw from Sudan's troubled north Darfur region following a number of attacks on its personnel there, MSF said Friday in Nairobi.

"After these violent attacks, we have had to suspend activities and evacuate all our staff from Tawila and Shangil Tobaya," said Monica Camacho, MSF head of mission in Darfur.

Some 65,000 people, most of them driven from their homes, will be left without medical assistance as a result of the decision.

"It was a difficult decision because this suspension of activities leaves the people with no medical care. But it is impossible for our teams to work and provide medical aid without a minimum guarantee of security and respect for humanitarian work," Camacho said.

Over the last week, MSF workers have been attacked and robbed in their compounds by armed men on two occasions.

Work in west and south Darfur would continue, MSF said. (dpa)
