U.N. Is Offered Help to Reach Crash Site

Angolan President Jose Eduardo dos Santos has promised to help a U.N. team reach the wreckage of two U.N.-chartered planes that recently crashed in a war zone with a total of 22 people on board, U.N. special envoy Benon Sevan said. However, Sevan did not win government assurances of a cease-fire so a U.N. rescue team can search for survivors. Meanwhile, four workers at a diamond mine, including a Briton and a Brazilian, were killed in an ambush by a band of gunmen believed to be rebels, a mine official said.
