In Iraq, kidnappers have killed an Egyptian working for the U.S. military, as a deadline looms for the threatened murder of four Western peace workers held for the past two weeks. A group calling itself The Swords of Truth says it is holding two Canadians, a Briton and an American. Two days ago it said it would kill them by Saturday unless thousands of prisoners were released from Iraqi jails.London and Washington have said they will not negotiate with the abductors and nothing has been heard from the group for 48 hours. The other two Westerners abducted recently are a female German archaeologist and a Frenchman who was dragged screaming from his home in Baghdad earlier this week. Since late last month eight foreigners have been abducted in Iraq.
