In October 1973, charges against two of the militants were dropped for insufficient evidence. A court of inquiry commenced trying the remaining six in June 1974. The court sentenced the six to life imprisonment before their sentences were reduced to seven years. The US government unsuccessfully lobbied the Sudanese government to put them to death. Sudanese President
Gaafar Nimeiry was on an official trip abroad during the incident and condemned it in the strongest terms on his return, stating that the perpetrators rewarded Sudan, which had provided peaceful sanctuary to Palestinian refugees, with the disturbance of Sudan's internal peace. He decided to delegate the punishment of the perpetrators to their compatriots and handed the six to the custody of the
Palestine Liberation Organization. The next day, the PLO sent the six to
Egypt, where they were to serve their sentences. In protest of Sudan's handling of this situation, the United States withdrew its ambassador to Sudan and froze economic assistance to Sudan in June. A new US ambassador returned to Sudan in November that year, and aid resumed in 1976. Three of the Black September militants disappeared from Egyptian custody and were never recaptured. The remaining three served out their sentences. The United States also tried to prosecute
Yasser Arafat in the United States for his role in the event. However,
John R. Bolton, then assistant attorney general at the U.S. Department of Justice, concluded in 1986 that legal jurisdiction for trying Arafat was lacking, as the appropriate statutory laws were not yet in force in 1973. In December 2006, the
United States Department of State released documents claiming that Arafat and the
Fatah party were aware of the plot before it was carried out, and had ordered the operation. The documents further alleged that US intelligence had sent a warning to the embassy beforehand, but it was not intercepted in time. ==See also==
