Turkey’s foreign minister says Ankara is closely monitoring an agreement between the Syrian government and a U.S-backed Kurdish-led armed group.

Kurdish-led forces that control large swathes of northern Syria said nine people from the same family were killed Sunday night in a bombing it blamed on Turkey.

Syria’s interim government says it has reached a landmark agreement with Kurdish-led forces to integrate them into state institutions as it tries to unify the country’s diverse communities after a decade of civil war.
