GENEVA (Reuters) - More than 23,000 refugees fleeing fighting in northern Syria have crossed into Turkey, the United Nations refugee agency said on Tuesday, quoting Turkish authorities.

Syrian Kurdish-led forces said they had captured a town at the Turkish border from Islamic State on Monday, driving it away from the frontier in an advance backed by U.S.-led air strikes.
