An Australian man has reportedly been killed while fighting against Islamic State (IS) militants in Syria.
Social media accounts belonging to Kurdish military units claim Australian volunteer soldier Jamie Bright died last week in the northern Raqqa countryside.
Mr Bright was fighting with the YPG, the Kurdish People's Protection Unit.
It is the main armed service of the Federation of Northern Syria - Rojava.
The YPG is primarily ethnic Kurdish, but it also recruits Arabs, Turks, and Westerners, Wikipedia reports.
As a guerrilla combat force, the YPG relies on speed, stealth, and surprise.
It relies heavily on snipers and backs them by suppressing enemy fire using mobile heavy machine guns.
It also uses roadside bombs to prevent outflanking maneuvers, particularly at night.
The YPG and HPG have also trained and equipped more than 1,000 Yazidis, who operate in the Mount Sinjar area as local defense units under their supervision.
The Department of Foreign Affairs said it is unable to confirm his death, but says Australians should not travel to Syria.
In a video posted on Twitter, Mr Bright said he had travelled to the area to help the people.
