The Angolan government accepted proposals by Zaire’s president, Mobutu Sese Seko, for monitoring a cease-fire in Angola’s 14-year-old civil war, according to an official statement. But U.S.-backed guerrillas, known as the National Union for the Total Independence of Angola, requested a week’s break in peace talks to consult with their leaders. Mobutu is mediating the talks in the Zairean capital of Kinshasa. The Angolan government did not release details. However, Mobutu said last week that they included installing a radio link between the Angolan capital of Luanda, Kinshasa and the guerrillas’ southeast Angolan bush headquarters.
