Eighteen American-backed fighters have mistakenly been killed in an airstrike by the US-led coalition in Syria.
Those who died south of the city of Tabqa on Tuesday were members of the Syrian Democratic Forces (SDF), said the Pentagon.
The SDF is an alliance of Arab and Kurdish fighters who are battling Islamic State.
The US said its "partnered forces" had requested an airstrike after identifying what they said was an IS "fighting position".
