U.S. Sends AWACS to Egypt In Wake of Attack on Sudan Libya Denies Omdurman Bombing Ethiopia Cancels Talks Libya Denies Omdurman Bombing The U.S. March 18 sent two Airborne Warning and Control System surveillance planes to Egypt in response to the bombing March 16 of the Sudanese city of Omdurman. U.S. Defense Department officials said President Reagan had authorized the AWACS deployment upon receiving a joint request from Egypt and the Sudan, which had a mutual defense treaty. Sudanese President Mohammed Gaafar el-Nimeiry March 16 accused Libya of responsibility for the bombing attack, which was apparently aimed at the main Sudanese radio station. The raid reportedly was carried out by a Soviet-built TU-22 bomber, which dropped five bombs without encountering any resistance from Sudanese forces. The bombs missed the radio station and transmitter but hit neighboring buildings, killing five people. U.S. and Sudanese officials said the bomber was based at an airfield in Kufra, Libya. Nimeiry said the bombing confirmed the complicity of Libya's leader, Col. Muammer elQaddafi, in efforts by Ethiopian-backed Sudanese separatists to overthrow the Nimeiry government. The insurgent movement, which originated in the Sudan's impoverished Christian and animist south, was seeking to end the traditional dominance of the country's Moslem north. Regional tensions had intensified, according to diplomatic sources, since Nimeiry's imposition of Islamic law in September 1983. [See 1983 World News Briefs: Sudan, 1983 Sudan: Army Mutiny Put Down] Libya March 18 denied responsibility for the air attack, according to the official news agency, JANA. Ambassadors to Tripoli from African countries had been told that the Sudan had fabricated the charge in an attempt to persuade the U.S. to provide military support against the southern rebels, JANA reported. The U.S. March 19 warned Libya against interfering with the AWACS. "We told the Libyans that we are deploying our own military aircraft in the region and any action against them could have serious consequences," according to State Department spokesman Alan Romberg. He said the warning had been conveyed through Belgium, as the U.S. and Libya did not have diplomatic relations. Romberg provided the first official explanation of the AWACS mission. "AWACS will be part of combined air defense operations being carried out by Egypt and the Sudan," he said. "The purpose of these operations is to deter sustained attacks by demonstrating that the three countries can rapidly put in place the assets necessary to deal with such aggression." (The U.S. had sent AWACS to Egypt in February 1983, reportedly to counter Libyan attempts to destabilize the Sudan. In August 1983, the U.S. had deployed AWACS in Egypt and the Sudan in response to Libyan military activity in Chad.

"If these planes have returned to facilitate, prepare, cover or protect any form of aggression against Libya," JANA said, "we warn that the Libyan Arab air force is capable of intervening in the skies where these aircraft operate and are also capable of reaching and destroying them." U.S. Secretary of State George Shultz, in a news conference March 20, said "it is a fact" that Libya had carried out the bombing raid on Omdurman, which he called "unprovoked aggressive behavior." Shultz said the attack was part of "a pattern of behavior on the part of Libya that is outside the pale of internationally acceptable behavior." Ethiopia Cancels Talks Ethiopia March 11 said it would not attend talks with the Sudan, which had been planned in an effort to ease tensions between the two countries. The talks had been scheduled to begin March 12 in Nairobi, Kenya. Lt. Col. Goshu Wolde, Ethiopia's foreign minister, accused the U.S. of a huge arms airlift to the Sudan and charged that the U.S. and the Sudan were in "collusion and conspiracy" against Ethiopia. "There is ample evidence that four to five planes a day are airlifting weapons from the U.S. to Khartoum, which is clearly in excess of its defense needs," he said. Ethiopia's announcement followed a series of discussions between the U.S. and the Sudan concerning a long-standing Sudanese request for U.S. military supplies. Maj. Gen. Umar Muhammad al-Tayyib, Sudan's first vice president and minister of state security, visited Washington Feb. 29-March 3 for meetings with top U.S. officials, including Vice President George Bush, Secretary of State George P. Shultz and Defense Secretary Caspar Weinberger. Tayyib March 5 said the U.S. had agreed to supply the military equipment requested by the Sudan. "The U.S. administration," Tayyib said, "has taken a political decision of supporting Sudan against this major conspiracy aimed at destabilizing Sudan's security and has decided to begin in the next few days airlifting weapons and defensive equipment directly from the United States to Khartoum to help the Sudanese armed forces defend Sudan's territory." The U.S. State Department the same day denied that it had agreed to an arms airlift and said it was still considering the Sudanese appeal. "No specific decisions have been made yet on either weapons systems or modes of delivery," State Department spokesman John Hughes told reporters. He said "the clear emphasis of our total aid program is on economic assistance, and we continue to believe that Sudan's problems can most effectively be addressed through economic means." U.S. ambassador-at-large Vernon Walters March 6 arrived in Khartoum for meetings with Sudanese President Nimeiry. Walters reportedly conveyed a message from President Reagan that the U.S. knew of "external support being given dissident elements and consider[ed] it unacceptable interference in Sudanese affairs." According to diplomatic observers, the U.S. was stressing Ethiopian and Libyan involvement in the Sudanese insurgency in an effort to avoid the appearance of American involvement in an internal Sudanese conflict. In related developments: Sudanese insurgents Feb. 2 attacked the U.S.-operated Chevron Oil Co. complex at Bentiu in the southern Sudan, killing three foreign workers and wounding seven. Chevron, which had suspended operations in the southern Sudan following the raid, March 8 announced plans to resume exploration in the Mugled area and possibly at several other sites. Guerrillas March 12 released West German Ursula Morson and her 18-month-old son, who had been held hostage for a month along with four foreign employees of the CCI construction company, a subsidiary of Grands Travaux de Marseille (GTM), a French construction firm. International organizations had appealed to the insurgents to free Morson, who was eight months pregnant. GTM, the secondlargest international company working in the Sudan, evacuated its personnel after the rebel attack on an irrigation project on the Jonglei canal Feb. 11 in which Morson and the others were captured. Sudanese guerrillas Feb. 13 staged a bazooka attack on a Nile River passenger steamer. Conflicting reports emerged following the attack, with the insurgents claiming they had sunk the steamer and were holding 222 soldiers captured on board. The official Sudanese press agency Feb. 15 said a fire had broken out on a barge trailing the steamer, which was carrying 300 passengers. On Feb. 18, the agency reported that 800 people had been aboard the steamer, and that all but 14 passengers and two crew members had been accounted for. The news agency the same day said government troops had killed 30 rebels who participated in the attack.
