United Nations ? The United Nations Security Council opened the door Friday to new economic, political or military sanctions against Sudan because of an attack by its troops on a U.N. peacekeeping convoy earlier this week.

The council said it “condemns in the strongest possible terms” Monday’s attack on U.N. peacekeepers by “elements of the Sudanese armed forces,” saying any such attack is unacceptable. Sudan has acknowledged its troops shot at a U.N. convoy in West Darfur, damaging an armored personnel carrier, destroying a fuel tanker truck and severely injuring a Sudanese driver.

Because of the attack, the council said in a statement that it “expresses its readiness to take action against any party that impedes the peace process, humanitarian aid or the deployment” of the U.N. force, known as UNAMID, made up of U.N. and African Union troops and other personnel.

The U.N. mission began on Jan. 1 and now stands at around 9,000 peacekeepers. It is supposed to grow to 26,000 and aims at finally deploying a robust force to stop the chaos.
