 The UN mission in Libya has urged leaders to stick to the December 24 timeline for presidential and legislative polls it hopes will help stabilize the war-battered nation. Libya has been struggling to move past the violence that followed the topling and killing of Muammar Gaddafi. A ceasefire between Eastern and Western factions last year led to a fragile unity government taking office in March with a mandate to take the country to elections. Part of an agreed roadmap was to hold elections on the same day. Foreign powers have been pushing for the elections to be held as shadowed after the date was agreed at UN-led talks last year.
