TRIPOLI, Libya (AP) — U.N. Secretary-General Ban Ki-moon traveled Saturday to Libya to support a reconciliation process between warring factions there, calling on renegade general fighting Islamist militias in its east to stop his operations and on armed groups to leave the capital’s airport.

Ban was in Libya days after the U.N. launched a reconciliation process that seeks to resolve the bloody rift that has left their oil-rich North African nation deeply split with two separate parliaments and governments.
