[Source: BBC News]The UN has called for an immediate stop to hostilities in Libya following a day of deadly clashes between political factions in the capital Tripoli. At least 23 people were killed and dozens more were wounded during the fighting, the health ministry in Tripoli said. The UN’s Libya mission said the fighting had included “the indiscriminate medium and heavy shelling in civilian-populated neighbourhoods” and called for an immediate ceasefire. But the stability that led to its prosperity has been shattered and Tripoli has seen frequent fighting between rival forces since 2011.
