Pope Francis on Sunday urged political and military leaders in Libya to end their hostilities and called on the international community to take “to heart” the plight of migrants trapped in the lawless nation. The Pope’s comments came as forces allied with a U.N.-supported government in the capital Tripoli are prearing to launch an attack on rival forces led by military commander Khalifa Hifter in the strategic coastal city of Sirte. If successful, it could help them seize key oil fields and facilities in Libya’s south.
