Isis announced his death using his war name Abu Musa al-Britani on social media, calling him a “martyr”.
Abdul Waheed Majeed, a father-of-three from Crawley, died in February last year when he drove a truck bomb into the gates of Aleppo prison in Syria and several other British fighters are believed to have died in battles and bombings.
An English language Isis guidebook put online by men claiming to be militants earlier this year described “martyrdom” as one of the options after completing basic training.
“They will be sent to battle to fight and gain experience, or gain martyrdom (if they want to do a martyrdom operation, they are put in a waiting list),” it said.
“Fighters will be given money, or may have brought some with themselves already. With this money they can buy more weapons, explosive-martyrdom belts, or even simply food like ice cream from the Souks (shopping centres) when they are free from battle and back in the city.”
Isis has made gains in Syria and Iraq in recent weeks, seizing the cities of Palmyra and Ramadi, prompting counter-offensives from government troops and international allies.
