TURKEY said yesterday US arms to Syrian Kurdish militia were a “threat” to its security that threatened a “crisis” in Nato.

Washington announced on Tuesday night it would funnel heavy weapons to the Syrian Democratic Forces (SDF), the forces dominated by the Kurdish YPG fighting Isis independently of the Bashar al-Assad government in northern Syria.

Turkish President Recep Tayyip Erdogan (pictured) said the “fight against terrorism should not be led with another terror organisation.”
