ANGOLAN authorities have issued an arrest warrant for Jonas Savimbi, the leader of Unita. Savimbi went back to war with Angola’s ruling MPLA government in 1998, after three years of peace in Angola. The country has been at war more or less continuously for twenty years. The most recent bout of fighting began after Savimbi failed to disarm in accordance with a peace agreement signed in Lusaka, Zambia in 1994. ”Crimes of armed rebellion, sabotage, traffic and the use of banned war machinery, and killing,” were cited on the warrant, according to Angolan officials. Unita rebels have recently come almost within artillery range of Luanda, Angola’s capital.
