'The son of Britain's Abu Hamza is reportedly trying to appeal the decision to revoke his British passport amid the furore of the case of ISIS bride Shamima Begum.
Sufyan Mustafa, 23, was stripped of his UK passport in 2017 after travelling to Syria to fight.
But at the end of last year he was said to have been stopped from boarding a flight to the UK from Turkey when his name was flagged as being on the terror watch list.
In his 2017 interview with al-Quds, the Arabic newspaper, Mustafa spoke of his irritation at being accused by the Government of being a terrorist. He also told of his “surprise” at his passport being revoked.
He said he would return to Britain when the régime of President Bashar al-Assad has fallen and the fighting has stopped.
He also questioned the Home Office decision, insisting he was fighting with a moderate group which was supported with British and American weapons.
He said: "Britain is the place where I was born and lived. I have never been a threat to national security in Britain and will not commit aggression on its population because our religion does not allow attacks on unarmed innocents."
Talking in 2017, Mustafa admitted his father, a 59-year-old cleric jailed for life after a trial in New York in 2015, had made mistakes, but added by way of explanation: "Who hasn’t when they believe in a cause?"
Mustafa said he had taken part in battles in Aleppo and on his Twitter feed he has written about the killing of regime forces.
He said: "I am a believer that the real battle will be after the fall of the régime, in the construction of Syria again and reform of the political and economic affairs and construction of public schools to study. The victory of the revolution will be when we see the people elect a representative government and take the country to a better future than it was."
In March 2017, Mustafa appeared in a jihadist propaganda video in which he both denounced Assad but also criticised ISIS for giving Islam a bad name.'
