UN Force Enters Indonesia: DILI, East Timor — U.N. forces on Wednesday flew into Indonesian territory to evacuate foreign aid workers after rioters stormed a U.N. office and killed three U.N. staffers, a peacekeeping spokesman said. Norwegian army Col. Brynar Nymo said four helicopters from the East Timor town of Suai flew to Atambua, West Timor, where hours earlier an angry pro-Indonesian mob attacked and burned the office of the U.N. High Commissioner for Refugees. The four choppers, including two gunships, safely evacuated 54 people to East Timor's border town of Balibo, he said.
