RWANDA . . . MOVING IN

Rwandan Prime Minister Faustin Twagiramungu said the new government's victorious guerrilla army will move into the French-protected "safe zone" when French troops leave on Monday. That move could activate the fears of several hundred thousand Hutu refugees huddled there, many of whom don't trust their old foes to spare the rod of revenge after Rwanda's civil war. U.N. officials, who had begged France to extend its Rwandan mission, today said the number of Hutus poised to flee to refugee camps across the Zairian border had reached "critical but not yet catastrophic" proportions. U.N. peacekeepers now believe they can effectively replace the French.
