IRBIL, Iraq: A British citizen fighting alongside Kurdish forces against the Islamic State group has been killed in Syria, a Kurdish commander said Wednesday.

Konstandinos Erik Scurfield, an ex-Royal Marine, was shot dead March 2 in the front-line village of Tel Khuzela, Kurdish commander Redor Khalil told The Associated Press.

Another foreign fighter battling with the Kurds, American Jordan Matson, said he was with the body on Wednesday and was working on getting the remains back to Britain.

“We’re trying to make contact with his mother to see what her wishes are,” Matson told the AP Wednesday. “Otherwise, he wished to be buried here under an olive tree.”

Matson said on his Facebook page that Scurfield also had Greek citizenship and had served in the Greek Army and as a British Royal Marine. Scurfield was 25 years old.

Dozens of foreign fighters have traveled to Syria and neighboring Iraq to fight with Kurdish militias battling the Islamic State group. Matson and four other foreign nationals told the AP last month that they arranged to join Kurdish forces through the Facebook page run by the People’s Protection Units, or YPG, the main Kurdish militia fighting in northern Syria.

At least one other foreign fighter, Australian Ashley Johnson, who went by the name of Ase, is known to have been killed fighting alongside the Kurds.
