Libya’s rival factions gathered on Monday in Tunisia for the beginning of the much-awaited political peace talks brokered by the United Nations, with a goal of drawing a roadmap to presidential and parliamentary elections. The gathering is the latest in efforts to end the political chaos that engulfed the North African nation after the 2011 overthrow and killing of Libyan dictator Moammar Gadhafi. The U.N. had selected 75 delegates from Libya to take part in the six-day forum at a luxury hotel in the Mediterranean town of Gammarth, just outside the capital of Tunis.
