Casting aside U.S. concerns about aiding extremist groups, Turkey and Saudi Arabia have converged on an aggressive new strategy to bring down Syrian President Bashar Assad.
The two countries — one a democracy, the other a conservative kingdom — have for years been at odds over how to deal with Assad, their common enemy. But mutual frustration with what they consider American indecision has brought the two together in a strategic alliance that is driving recent rebel gains in northern Syria, and has helped strengthen a new coalition of anti-Assad insurgents, Turkish officials say.
