A former warlord was sentenced to 20 years behind bars in Switzerland on Friday, becoming the first Liberian to be convicted over war crimes committed during his country's bloody conflict a generation ago. Switzerland's Federal Criminal Court found Alieu Kosiah, 46, guilty of multiple atrocities, including killings, rape and using child soldiers, committed during the first of Liberia's back-to-back civil wars, which together killed some 250,000 people between 1989 and 2003. The verdict marks the first time a Liberian has been convicted -- either in the west African country or anywhere else -- of war crimes committed during the conflict. nl/vog/spm
