RIYADH, Saudi Arabia — For months, Saudi Arabia and Qatar have been funneling money and small arms to Syria’s rebels but have refused to provide heavier weapons, like shoulder-fired missiles, that could allow opposition fighters to bring down government aircraft, take out armored vehicles and turn the war’s tide. While they have publicly called for arming the rebels, they have held back, officials in both countries said, in part because they have been discouraged by the United States, which fears the heavier weapons could end up in the hands of terrorists. As a result, the rebels have just enough weapons to maintain a stalemate, the war grinds on and more jihadist militants join the fray every month.
