Isis is developing sleeper cells in the UK using secret online terror guides that teach would be jihadis how to stay under the radar
- Arabic manual hidden behind innocent looking websites on classic cars
- Step-by-step instructions on how to avoid detection by security services
- Tells would-be western jihadists how to delete their digital footprint
- Police and government have said an attack on the UK is almost inevitable
The document, hidden behind innocent looking websites on classic cars and art, details how to plan a strike in the UK without detection.
The Arabic guide, said to be written by a number of different authors, will further ignite fears that the terrorist group has placed sleeper cells in the UK, who are laying in wait to carry out attacks.
The document includes basic instructions for wannabe western jihadists on how to delete their digital footprint to avoid detection.
The manual says that if used correctly it would be ‘impossible’ for the counter terrorism services to access ‘important information on the Muslim brothers,’ according to the Mirror.
Among the lessons are how to conceal a computers unique IP address and the method for disarming a smartphone’s tracking software.
The text is also said to give step-by-step instructions on how to send encrypted messages and advises how to access the ‘dark web,’ to research and plan attacks.
‘This is just the tip of the iceberg,’ a spokesman for Global Vigilance, an offshoot of the hacking group Anonymous, who discovered the material told the newspaper.
‘The training material brings home the level of sophistication they posses.’
Home SecretaryTheresa May and senior British police chiefs have previously said that a terrorist atrocity involving an ISIS-style beheading or bomb attack on civilians is now ‘almost inevitable’.
Belgian national Dimitri Bontinck, who is known as the ‘Jihadi Hunter’ for rescuing youths from IS, has also said attacks are likely.
‘I’ve been told by very influential sources that they have sleeper cells over here, and are preparing to unleash their war in Europe,’ he said last year.
This is not the first time that IS has published basic guides for its radicalised recruits.
A 50-page manual has been circulated online called Hijrah, meaning ‘holy emigration’, which includes details of safe houses and routes for Western wannabe jihadists and has been compared to a gap year travel guide.
Another, titled Questions And Answers On Taking Captives And Slaves, instructs IS fighters on how to buy and sell women and girls who have been captured in war as booty.
There are also Arabic manuals that give advice to Jihadi mothers on how to raise a new generation of ‘Caliphate cubs’ trained for war.
BRITAIN’S HOMEGROWN JIHADISTS AND HOW UP TO 1,000 OF THOSE WHO FOUGHT FOR ISIS IN SYRIA ARE ALREADY BACK IN THE UK
Between 500 and 2,000 Britons are believed to have fled the UK to fight for ISIS – and around half may already be back home.
Experts believe that all of them will have been taught how to make bombs and use weapons in the hope they may launch attacks here.
Many young women have also left for Syria to fight and marry jihadists, believing they can have a better life there.
A major problem has been the relative ease they have been able to fly to Istanbul in Turkey and jump on a bus to get into neighbouring Syria.
Here are some of the most notorious Britons who left to join ISIS:
Mohammed Emwazi, the British jihadi now known as Jihadi John
It is thought that during the early stages of the conflict Emwazi was a prison guard, along with three other Britons, leading to them being nicknamed The Beatles.
Escaped captives had given him the name John, after Beatles lyricist John Lennon, which eventually became Jihadi John.
In previous interviews, French hostages have described how Emwazi talked to them about al-Shabaab and the war in Somalia, making them watch videos of the fighting there.
But it appears he then chose ISIS instead and fled to Syria.
Emwazi first rose to international attention in August 2014 when he appeared in a video showing the beheading of American journalist James Foley.
Since then he has been seen in videos showing the beheading of Steven Sotloff, another American journalist, Peter Kassig, a former U.S. solider.
Also murdered at the hands of Emwazi were David Haines and Alan Henning, two British aid workers, and Japanese hostages Kenji Goto and Haruna Yakuwa.
Abdel-Majed Abdel Bary
Abdel-Majed Abdel Bary, 23, rose to prominence after he was pictured holding a decapitated head while standing in Raqqa’s central square.
Bary is a former rapper who once had his music played on Radio One.
He is understood to have walked out of his family’s £1million home in Maida Vale, west London, last year to join ISIS, telling them he was ‘leaving everything for the sake of Allah’.
Friends said Bary – an aspiring rapper on the ‘grime’ music scene – grew increasingly radical and violent after mixing with thugs linked to hate preacher Anjem Choudary.
He has posted a series of photographs online, including shots of him masked and posing with guns under the title ‘soldier of Allah’.
In other messages he called on Allah to ‘grant us martyrdom’, and praised Osama Bin Laden. Bary, whose music has featured on Radio 1, is one of six children of Adel Abdul Bary, 53.
Bary Snr was extradited from Britain to the US in 2011 after an eight-year legal battle that made him a cause celebre of the Left as lawyers took his publicly funded case to the European Court of Human Rights in Strasbourg.
Investigators believe Bary Snr was one of Bin Laden’s closest lieutenants in the infancy of Al Qaeda and ran a London cell of the terror network.
He faces life in prison if convicted of involvement in the bombings of US embassies in East Africa in 1998.
The young Briton boasted of fighting ‘5-star jihad’ in Syria but was killed.
Ifthekar Jaman, 23, died in 2013 in a battlefield clash 2,000 miles from his Hampshire home last December.
He was one of an estimated 350 British men to have taken up arms with Al Qaeda-linked groups in Syria – where they are known as British Kataa’ib, meaning British Brigade.
Jaman declared he was ready to die as a martyr, vowing: ‘I don’t plan to come back. Life is for the hereafter… it’s an eternal paradise so the sacrifice is small.’
He also urged fellow Britons to join him, using his Twitter account to glory in his hate-filled missions.
He described fighting in Syria as ‘5-star jihad’ because of its ‘relaxing’ nature.
Photographs showed Jaman – a supporter of fanatical British cleric Anjem Choudary – apparently manning armed checkpoints in the Middle Eastern war zone just before his death.
