ROME - Italy is seeking to host an international meeting in Rome on Dec. 13 to accelerate a political settlement between rival factions in Libya that would open the way to fight Islamic State militants there, the Foreign Minister said on Wednesday."The fact is we don't have much time, and we don't want to give time to Islamic State," Foreign Minister Paolo Gentiloni said in the Senate. "Italy is at work to bring the community together to make a final push."In the four years since the Muammar Gaddafi regime was overthrown, former rebel brigades have turned on each other, vying for power. Islamic State militants have gained ground, and now control the city of Sirte.
