The last of a group of British men who fled their hometown of Portsmouth to fight alongside ISIS in Syria has reportedly been killed.
Assad Uzzaman, 25, travelled to Syria in October 2013 alongside four other men from the port town.
His death was reported by Shiraz Maher, a senior fellow at the International Centre for the Study of Radicalisation and Political Violence at King's College London.
Though little is known about Uzzaman's activities in Syria, he appeared in some ISIS official videos and is understood to have gone under the moniker "Abu Abdullah al Britani".
The other members of the group from Portsmouth, whom some have referred to as the "Britani Brigade Bad Boys", were Mehdi Hassan, Mamunur Roshid, Hamidur Rahman, and Mashudur Choudhury, all aged between 19 and 31.
Hassan, Roshid, and Rahman reportedly died fighting in Syria, while Choudhury is currently serving a jail sentence in the UK.
The men travelled to the region together shortly after another Portsmouth man, Ifthekar Jaman, 23, left the UK to join ISIS. He died in 2013, making him one of the first Britons confirmed to have been killed while fighting for the group.
Maher said Uzzaman could be the 50th Briton known to have been killed while fighting in Syria, although he was not certain of this.
"The death of the final member of the Portsmouth group is the closing of a fascinating chapter of Britain's Syrian jihad," Raffaello Pantucci, a senior research fellow at the Royal United Services Institute, told The Telegraph.
"The sad reality of their deaths, however, shows that while these young men may be drawn to this conflict for a wide array of sometimes even noble reasons, they were not able to turn the tide of the conflict and ultimately simply became cannon fodder in ISIS's confrontation with everybody from the Assad regime to the West.
"With their deaths, we are left with little changing in the war in Syria, saddened families back in the UK and simply a growing roster of young Britons who are fighting in this seemingly intractable conflict."
