A panel of U.N. experts has asked the Security Council to impose sanctions on people it accuses of blocking peace in Sudan's Darfur region.
The panel's report says the council should consider placing a travel ban and a total asset freeze on figures in the Sudanese government, Darfur rebel groups, and government-backed militias.
The Security Council authorized the sanctions last March but has yet to impose them on anyone.
News agencies that obtained the report say it was scheduled to go to the full council this week but was temporarily blocked by Qatar and China.
Tens of thousands of people in Darfur have been killed and some two million displaced during three years of conflict between the rebels and Sudan's government.
Several rounds of peace talks have failed to yield any substantial progress.Some information for this report was provided by AP and Reuters.
