United Nations (AP) -- Democratic Presidential Hopeful Joseph Biden has renewed his call for US troops to help quell continued violence in the Sudan's volatile Darfur region.
An estimated 200,000 people have been killed and more than two million others have been displaced.
Biden says if he had the authority, he'd impose a no-fly zone and commit forces to stop government-backed Arab militias blamed for atrocities.
The Sudan's UN Ambassador said sending in troops was not necessary and insists "the peace process is moving”.
President Bush warned a month ago that he would tighten economic sanctions and impose even more restrictions unless Sudan's president started making definite moves toward peace.
