Two American men fighting for the Islamic State (IS) group in Syria have been captured, according to a US-backed Syrian militia alliance.
The Syrian Democratic Forces said on Sunday they had captured Warren Christopher Clark from Houston, Texas, and Zaid Abed al-Hamid during fighting.
According to the alliance, the men were caught planning a terrorist attack on fleeing Syrian civilians.
They were arrested along with suspected fighters from Ireland and Pakistan.
Pentagon spokesman Sean Robertson told US media: “We are aware of open source reports of reportedly American citizens currently in custody who were believed to be fighting for Isis.
However, we are unable to confirm this information at this time.”
US officials have previously estimated that the Syrian Democratic Forces (SDF) have more than 700 foreign fighters in custody coming from around 40 different nations.
The men were arrested along with two Pakistanis and one Irishman in an operation to clear a region of northern Syria of remaining IS fighters, says the SDF.
