The body of an American hostage has been found in Iraq.
Authorities say there were signs that Christian peace activist Tom Fox was beaten before he was killed. His body was found Thursday with bound hands and gunshot wounds.
A friend and colleague of the slain man told a news conference in the U.S. state of Virginia on Saturday that Fox worked with Iraqi prisoners who were held "out of sight and with no avenue for communication." He said Fox and the other Christian activists worked for peace and deplored violence.
Fox was one of four Western aid workers from the North American-based Christian Peacemaker Teams who were abducted in Iraq in November. The fate of the others - two Canadians and a Briton - is not known. They were shown without the American in a videotape aired on Arabic television this week.
Meanwhile, gunmen in Baghdad killed a journalist for Iraqi television and his driver. The U.S. military also said coalition forces detained a number of suspected insurgents in raids.
