In late October 1992, Savimbi dispatched UNITA Vice President Jeremias Chitunda and UNITA senior advisor Elias Salupeto Pena to Luanda to negotiate the details of the run-off election. On 2 November 1992 in Luanda, Chitunda and Pena's convoy was attacked by government forces and they were both pulled from their car and shot dead. Their bodies were taken by government authorities and never seen again. The MPLA offensive against UNITA and the FNLA has come to be known as the Halloween Massacre where over 10,000 of their voters were massacred nationwide by MPLA forces. Alleging governmental electoral fraud and questioning the government's commitment to peace, Savimbi withdrew from the run-off election and resumed fighting, mostly with foreign funds. UNITA again quickly advanced militarily, encircling the nation's capital of Luanda.
