In a rare interview, Mazloum Kobani told Reuters that Washington had made “serious attempts” to prevent a Turkish offensive against Kurdish fighters who control a swathe of northern Syria at the Turkish border, but the United States should ramp up its efforts further. The SDF, which is spearheaded by the Kurdish YPG militia, has been at the heart of the U.S.-backed fight against Islamic State. SDF commander-in-chief Kobani warned that a Turkish assault would tie up YPG fighters who are currently fighting Islamic State remnants in eastern Syria, allowing the jihadists to spread again.
