Two British men have reportedly been killed fighting for Islamic State (IS) in Syria.

Abu Abdullah al Habashi, 21, and Abu Dharda, 20, both from London, are thought to have died in the Syrian border town of Kobani.

Kurdish fighters have been defending the town from an IS onslaught with the assistance of American air strikes.

Mr al Habashi is believed to have made comments supporting IS on social media and appeared in at least two propaganda videos put out by the extremist group.

He grew up in north London in a British-Eritrean family, and converted to Islam when he was 16, the BBC reported.

The UK has advised for some time against all travel to Syria, where all UK consular services are suspended

Mr al Habashi told the BBC in August that he was at the “forefront” of fighting and claimed he was one of a few British Jihadis who have fought with IS in both Syria and Iraq.

His family tried to convince him to return home but he said he was happy in the Middle East and there was “no going back”.

Mr Dharda, who comes from a British-Somali background and grew up in west London, is understood to have travelled to Syria in December 2013, entering via Turkey.

It is thought that 500 Britons have joined the conflict in Syria and a round 27 are understood to have lost their lives after joining the Jihadis.

A Foreign Office spokesman said: “We are aware of reports of the death of two British nationals in Syria.The UK has advised for some time against all travel to Syria, where all UK consular services are suspended.”

“As we do not have any representation in Syria, it is extremely difficult to get any confirmation of deaths or injuries.”
