both government and SPLA-held areas of the Sudan, and widespread starvation was averted. Phase II of OLS to cover 1990 was approved by both the government and the SPLA Sudan faced a 2-year drought and food shortage across the entire country. The US, UN, and other donors attempted to mount a coordinated international relief effort in both north and south Sudan to prevent a catastrophe. However, due to Sudan's human rights abuses and its pro-Iraqi stance during the Gulf War, many donors cut much of their aid to the Sudan. In a similar drought in 2000–01, the international community again responded to avert mass starvation in the Sudan. International donors continue to provide large amounts of humanitarian aid to all parts of the Sudan. The US government's Sudan Peace Act of 21 October 2002 accused Sudan of genocide for killing more than 2 million civilians in the south during the civil war since 1983. Arms suppliers Sudan relied on a variety of countries for its arms supplies. Following independence, the army was trained and supplied by the British. However, after the 1967 Six-Day War, relations were cut off, as were relations with the United States and West Germany. From 1968 to 1972, the Soviet Union and COMECON nations sold large numbers of weapons and provided technical assistance and training to Sudan. At this time the army grew from a strength of 18,000 to roughly 50,000 men. Large numbers of tanks, aircraft, and artillery were acquired, and they dominated the army until the late 1980s. Relations cooled between the two sides after the 1971 Sudanese coup d'état attempt by Hashem al Atta, and the Khartoum government sought to diversify its suppliers. The Soviet Union continued to supply weapons until 1977, when their arms aid to the Marxist military junta in Ethiopia during the Ogaden War angered the Sudanese sufficiently to cancel their deals and expel Soviet military advisors. The People's Republic of China was the main supplier in the late 1970s. Egypt was the most important military partner in the 1970s, providing missiles, personnel carriers, and other military hardware. At the same time military cooperation between the two countries was important. U.S.-aligned countries resumed supplying Sudan in the mid-1970s. The United States began selling Sudan a great deal of equipment around 1976, hoping to counteract Soviet support of Marxist Ethiopian government, Libyans and Somalia (before 1977). Military sales peaked in 1982
