Following the 1991 Bicesse Accords, signed in Lisbon, United Nations-brokered elections were held, with both Savimbi and dos Santos running for president in 1992. Failing to win an overall majority in the first round of balloting, and then questioning the election's legitimacy, Savimbi and UNITA returned to armed conflict. Fighting resumed in October 1992 in Huambo, quickly spreading to Angola's capital, Luanda. It was here that Jeremias Chitunda, UNITA's long-time vice-president and other UNITA officials were killed while fleeing the city culminating in the Halloween Massacre. Following Chitunda's death, UNITA defensively moved their base from Jamba to Huambo. Savimbi's 1992 decision to return to combat ultimately proved a costly one, with many of Savimbi's U.S. conservative allies urging Savimbi to contest dos Santos electorally in the run-off election. Savimbi's decision to forego the run-off also greatly strained UNITA's relations with U.S. President George H. W. Bush.
