after the Soweto uprising of 1976 in South Africa saw thousands of students – inspired by Black Consciousness ideas – cross the borders to seek military training. MK guerrilla activity inside South Africa increased steadily over this period, with one estimate recording an increase from 23 incidents in 1977 to 136 incidents in 1985. In the latter half of the 1980s, a number of South African civilians were killed in these attacks, a reversal of the ANC's earlier reluctance to incur civilian casualties. Fatal attacks included the 1983 Church Street bombing, the 1985 Amanzimtoti bombing, the 1986 Magoo's Bar bombing, and the 1987 Johannesburg Magistrate's Court bombing. Partly in retaliation, the South African Defence Force increasingly crossed the border to target ANC members and ANC bases, as in the 1981 raid on Maputo, 1983 raid on Maputo, and 1985 raid on Gaborone. During this period, MK activities led the governments of Margaret Thatcher and Ronald Reagan to condemn the ANC as a terrorist organisation. In fact, neither the ANC nor Mandela were removed from the U.S. terror watch list until 2008. The animosity of Western regimes was partly explained by the Cold War context, and by the considerable amount of support – both financial and technical – that the ANC received from the Soviet Union. Negotiations to end apartheid From the mid-1980s, as international and internal opposition to apartheid mounted, elements of the ANC began to test the prospects for a negotiated settlement with the South African government, although the prudence of abandoning armed struggle was an extremely controversial topic within the organisation. Following preliminary contact between the ANC and representatives of the state, business, and civil society, President F. W. de Klerk announced in February 1990 that the government would unban the ANC and other banned political organisations, and that Mandela would be released from prison. Some ANC leaders returned to South Africa from exile for so-called "talks about talks", which led in 1990 and 1991 to a series of bilateral accords with the government establishing a mutual commitment to negotiations. Importantly, the Pretoria Minute of August 1990 included a commitment by the ANC to unilaterally suspend its armed struggle. This made possible the multi-party Convention for a Democratic South Africa and later the Multi-Party Negotiating Forum, in which the ANC was regarded as the main representative of the interests of the anti-apartheid movement. However, ongoing political violence, which
