WASHINGTON (Reuters) - A U.S. judge on Monday handed down lengthy prison terms to three former Blackwater guards convicted in the 2007 massacre of 14 unarmed Iraqis, closing a chapter of the U.S. war in Iraq that tested relations between the two countries. Paul Slough, Evan Liberty and Dustin Heard were sentenced to 30 years each for voluntary and attempted manslaughter. (Reporting by Lisa Lambert; Editing by Peter Cooney)
