WASHINGTON, Oct 1, 2007 (AFP) - The United States on Monday warned both the Sudanese government and rebel groups in Darfur of new sanctions if they continue to flout a ceasefire, after at least 10 peacekeepers were killed.

Washington also called for the deployment as soon as possible of a 26,000-strong joint African Union-United Nations force to take over peacekeeping from nearly 6,000 under-equipped and under-funded AU troops.
