"Darfur needs peacekeepers to stop the killing. In the meantime, we are taking advantage of satellite technology to tell president al-Bashir that we will be watching closely to expose any new violations," he said in a statement.

"Our goal is to continue to put pressure on Sudan to allow the peacekeepers to deploy and to make a difference in the lives of vulnerable civilians on the ground in Darfur."

More than 200,000 people are believed to have died and two million driven from their homes since the conflict between ethnic African rebels and the government, backed by the Arab Janjawid militia, began in 2003.

Khartoum disputes those figures, saying 9,000 people have died, and rejects accusations of genocide.

Joint force
 
The UN Security Council last year adopted a resolution to deploy a 23,000-strong joint UN-African Union (AU) force but al-Bashir has previously only agreed to the deployment of 3,000 UN police and military personnel to aid the AU force of about 7,000.

Representatives from the government in Khartoum, the UN and the AU reached a tentative agreement on the force during a meeting in Addis Ababa on Wednesday.

The deal now needs to be endorsed by the African Union's Peace and Security Committee as well as the Security Council.

The images for the Eyes on Darfur website come from commercial satellites and would allow activists to track developments as they occur, Amnesty said. While the images would not be live, they would only be a matter of a few days old.
  
Lars Bromley, from the American Association for the Advancement of Science, which advised Amnesty on satellite imagery, said the images could show destroyed huts, massing soldiers or fleeing refugees.

"The technology allows Amnesty International to expand its traditional role of shining a light on human rights violations," Ariela Blatter, director of the Crisis Prevention and Response Centre at Amnesty USA, said.
  
Images of abuses could also be used in any future prosecutions, she added.
