The last of a group of young men who travelled from Portsmouth to fight with Islamic State (IS) has died, it was claimed.
Assad Uzzaman, 25, was one of five men who styled themselves the Britani Brigade Bangladeshi Bad Boys and travelled to Syria to fight as jihadis.
The group were spotted on camera walking through Gatwick airport in October 2013 as they headed for the war-torn country.
Of the group four are now dead and a fifth, Mashudur Choudhury, is serving a prison term in the UK.
A sixth man, Ifthekar Jaman, was one of the first Britons to join IS and encouraged others to fight with him in Syria. He was killed in December 2013.
Uzzaman - Jaman's cousin - is thought to be the 50th Briton killed while fighting in Syria and Iraq.
His death was reported by Shiraz Maher, a senior research fellow at the International Centre for the Study of Radicalisation (ICSR) at King's College in London, which monitors social media accounts of alleged jihadists.
He said: "The last of the Portsmouth cluster of fighters with Islamic State, Assad Uzzaman (Abu Abdullah) has died."
Mr Maher said the exact nationality of one of those on the ICSR's database was unclear, so the milestone of 50 Britons may be under dispute.
