KUWAIT CITY (AP) — An Arab summit that ended Wednesday exposed cracks in what was once solid Arab support for Syrian rebels, with Saudi Arabia and Qatar divided over which factions to back and Syria’s neighbors increasingly expressing fatigue with the flood of refugees from the country’s civil war.

The Syrian opposition used the two-day gathering in Kuwait to plead for its allies to unite in helping it at a time when Assad’s forces have made gains on the ground and prospects for a negotiated settlement of the three-year-conflict have become remote.
