A former Royal Marine has become the first Briton to be killed while fighting alongside Kurdish forces against Islamic State in Syria, a Kurdish militia has told the BBC.
The Kurdish Popular Protection Units (YPG) named him as Konstandinos Erik Scurfield, from Barnsley.
A British pro-Kurdish activist said he had informed Mr Scurfield's family of the death, at the request of the YPG.
The Foreign Office said it was "aware of reports" of a Briton dying in Syria.
The YPG said the "British volunteer martyr" died in an area west of the city of Qamishli on Monday.
