Abu Hamza's son 'trying to appeal' decision to revoke British passport after travelling to Syria to fight

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 Isil bride Shamima Begum.

Sufyan Mustafa, 23, was stripped of his UK passport in 2017 after travelling to Syria to fight with jihadists.

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.

Now, a source told The Sun he is trying to overturn the Home Office decision to take away his British citizenship.

The insider told the paper Mustafa has been told he can travel to Morocco, but that he doesn't want to.

International law forbids nations from making people stateless by revoking their only citizenship, but the Home Office in 2017 knew Abu Hamza's ninth child had dual nationality through his Moroccan heritage.

When he had his British passport revoked Mustafa, 23, whose father is in jail in the US after being convicted of a series of terrorism charges, complained in an interview with an Arabic newspaper of his plight.

He had previously pleaded for the option of coming back to his home in west London.

Mustafa was fighting alongside rebel units after fleeing Britain in 2013 following the extradition of his father to America to stand trial.

He denied fighting with Islamic State of Iraq and the Levant or with forces loyal to al-Qaeda, although sources said in 2017 the decision to revoke his passport was "not taken lightly".

It is unclear for which rebel group Mustafa was fighting, but he is now understood to be in Turkey having been given a safe passage.

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 regime 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 regime, 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 Isil for giving Islam a bad name.

Abu Hamza, who rose to notoriety after becoming imam of the Finsbury Park mosque, in north London, in 1997,  has been serving his sentence in solitary confinement at a high-security prison in Florence, Colorado.

He was extradited to the US seven years ago after the British government spent a decade trying to kick him out of the country.
