Two British men have reportedly been killed while fighting alongside Islamic State militants in Syria.
The men - known as Abu Abdullah al-Habashi, 21, and Abu Dharda, 20 - were from London.
IS sources and social media accounts associated with the group suggest they died in recent days in US air strikes in the border town of Kobane.
About 27 Britons are understood to have lost their lives after joining the jihadists.
The reports of the men's deaths could not be independently verified and the BBC was unable to contact their families.
Al-Habashi grew up in north London in a British-Eritrean family and converted to Islam when he was 16.
