Libya: World powers urge fair trial for captured Gaddafi son

World powers have urged Libya to work with the International Criminal Court and ensure a fair trial for Seif al-Islam, son of slain leader Muamar Gaddafi who was arrested after months on the run. Seif, wanted by the ICC for crimes against humanity allegedly committed in crushing anti-regime protests, was captured in Libya's far-flung Saharan south early on Saturday in a trap set by fighters of the Zintan brigade.
