CAIRO — Sudanese rebels have targeted energy assets in the war-torn province of Darfour.

A rebel group reported an attack on the Abu Jabra oil field in southern Darfour on Nov. 27. The National Redemption Front said a military garrison deployed at the field surrendered and that an army helicopter was shot down. Abu Jabra has a production output of 10,000 barrels per day, Middle East Newsline reported.

"The government garrison guarding the oil field was totally destroyed," the rebel group said in a statement. "Numerous soldiers, including high-ranking officers and generals, have surrendered."

The Sudanese military acknowledged a rebel attack on Abu Jabra. But a military spokesman said the rebels sustained heavy casualties and withdrew. Sudan expects $4 billion in oil revenues in 2006.
