Angola held a presidential election in 1992. In the first round dos Santos officially received 49.57% of the vote and Savimbi won 40.6%. Savimbi said the election had neither been free nor fair and refused to participate in the second round. International observers, however, affirmed that the elections had been largely free and fair. Savimbi, along with eight opposition parties and many other election observers, said the election had been neither free nor fair. The MPLA massacred over ten thousand UNITA and FNLA voters nationwide in a few days in what was known as the Halloween Massacre. UNITA renewed its guerrilla war, capturing five of Angola's eighteen provincial capitals.
