A US citizen fighting alongside Islamic State terror group militants in Syria has been captured, the Daily Beast reported Thursday.

Several US military officials told the website that Kurdish soldiers belonging to the Syrian Democratic Forces caught the American and he has now been detained.

“We are aware of the report that a U.S. citizen believed to be fighting for ISIS surrendered to Syrian Democratic Forces on or about Sept. 12,” ​a US military ​spokesman, Maj. Earl Brown​, told the Daily Beast.​

“We defer to the U.S. Department of Justice and the Government of Iraq on this issue. The Coalition’s mission is to defeat ISIS in Syria and Iraq, and we will pursue ISIS fighters regardless of nationality,” he said.

​Later Thursday, a spokesman for the US-led coalition fighting the terror group in Syria and Iraq​ said any detainees would be “transported humanely” to the custody or their nation’s authorities and referred further questions to the State Department.

The US citizen, who’s name is not know, is not the first American to be caught while fighting with IS.

​In March 2016, ​M​ohammad Jamal Khweis, who lived in the Washington, DC, suburbs surrendered to Kurdish forces in Iraq. ​
