Washington, April 28 : Mia Farrow thinks that U. S. president Barack Obama has not done enough for the people of Darfur.

Farrow, who started her three-week hunger strike on Monday to draw attention to the humanitarian crisis in the war-torn Darfur region of Sudan, says Obama has not kept the promises he made during the elections.

"During the campaign trail both he (Obama) and Biden made a lot of promises to help the region of Darfur, and nobody voted for him more excitedly than I but nothing has been done," Fox News quoted her as saying.

"Before, there were pre-election promises from Obama concerning the people of Darfur; this was before the expulsion of the aid workers. He even visited the refugee camps in Eastern Chad; he knows very well what the situation is.

"I fully appreciate that his plate is overflowing, but he could have appointed an envoy much earlier, he didn't apply an envoy until really late in the game and so the envoy went over and said `I''m here to listen and learn'.

"I just found that extremely dispiriting, while it's commendable to listen and learn, one would have hoped our envoy could have hit the ground running and already done his learning before he arrived in Sudan," she added. (ANI)
