A British IS fighter who died in a suicide bomb attack on Iraqi forces in Mosul is a former Guantanamo Bay detainee, the BBC understands.
The self-styled Islamic State group said two days ago that Abu-Zakariya al-Britani detonated a car bomb at an Iraqi army base in Tal Gaysum, south-west of Mosul.
He is believed to have been originally known as Ronald Fiddler.
Fiddler, 50 and from Manchester, was sent to Guantanamo Bay in 2002.
He had been seized by US forces in Pakistan in 2001, before being sent to Guantanamo.
US interrogators found he provided useful information to them about the Taliban’s methods, and he was released after two years.
The Daily Mail reported Fiddler received a million pounds in compensation from the government when he came back to the UK.
