Bulawayo, Zimbabwe — A dusk-to-dawn curfew was declared in Entumbane township after bloody guerrilla battles killed 43 people and injured 300 more. The township remained tense as scores of armed guerrillas carried rocket-launchers, machineguns, and Soviet-type assault rifles. Prime minister Robert Mugabe blamed Home Affairs Minister Joshua Nkomo's followers for provoking factional tension during weekend rallies by government ministers from Mr. Mugabe's ZANU-PF party. But Mr. Nkomo said inflammatory statements by Mr. mugabe's aides had sparked the clashes. The fighting and subsequent accusations by Mr. Mugabe and Mr. Nkomo brought relations between the coalition partners to their lowest point in years. The latest casualties bring to more than 65 the number of deaths in factional and political violence since Zimbabwe's independence from Britain in April.
