U.S. tries to stop feuding allies from unravelling Syria strategy

WASHINGTON (Reuters) - The United States scrambled on Monday to get its feuding allies, Turkey and Kurdish YPG militia, to focus their firepower on Islamic State instead of each other after clashes that have threatened to unravel America's war strategy in Syria.

Turkey, which has long viewed Kurdish militants as its top security threat, upended U.S. assumptions about the conflict by launching a major push last week into northern Syria that has included areas controlled by the U.S.-backed Syrian Democratic Forces (SDF), which includes experienced Kurdish YPG fighters.
