Warnings add to growing fears of attacks in UK following Paris massacre

Security sources confirmed they are seeing shift in terror group's tactics

Orders were sent over the past few days on encrypted messaging sites

Instead, they are being told to stay in Britain and wait for signal to attack

British jihadis are being ordered by Islamic State to forget travelling to Syria, remain in the UK and wait for a signal to attack.

Days before the Paris massacre, UK-based jihadis were being told of plans for imminent attacks in both France and Britain, messages seen by the Mail Investigations Unit suggest.

They are being advised not to risk travelling to Syria but to stay hidden in Britain until ISIS commanders give ‘the signal’ to strike.

Increased security: There has been increased security across Britain in the wake of the Paris massacre. Above, heavily-armed police officers are seen stationed at London's St Pancras station earlier this week

Special forces have been deployed to some of London's landmarks and busiest spots, including the Eurostar

The orders, sent over the past few days on encrypted messaging sites, are almost impossible to verify. But security sources confirmed they are seeing a shift in ISIS tactics.

The warnings will add to growing fears of attacks in the UK following the Paris massacre eight days ago in which 130 people were killed.

The Mail Investigations Unit has been shown messages sent to a radicalised individual in the UK over the past two weeks encouraging would-be fighters to launch terror attacks in Britain.

The UK-based extremists are being asked what weapons they have and how much ammunition.

They are told to stay in contact with ISIS online, and wait for further instructions on where and when to launch attacks.

They are also being advised on how to avoid detection by security services and how to recruit other young people.

FLEEING TO A WAR ZONE: 700 BRITONS HAVE TRAVELLED TO JOIN ISIS This year, at least 700 people have travelled from Britain to Syria to fight for ISIS. This figure includes many young women, and even entire families. In June, Bradford sisters Khadija, Sugra and Zohra Dawood travelled to the war-torn country with their nine children in an apparent bid to join the terror group. And last December, Sharmeena Begum became one of the youngest British teenagers to join ISIS when she fled from her home in East London and travelled to Syria aged 15. Three months later, three of her closest school friends – Amira Abase, 16, Kadiza Sultana, 16, and Shamima Begum, 15 – also boarded flights to Syria, triggering an international search to rescue them. The girls are believed to have married ISIS fighters. Neither they, nor Sharmeena, have been heard from since. One of the most high-profile British women to have joined the terror group is Sally Jones, who abandoned her family in Chatham, Kent, to live with her ISIS toyboy in Raqqa. It recently emerged that Jones, now dubbed 'Mrs Terror' and the 'White Widow', has been put on a government list of the most dangerous British recruiters for Islamic State. And last month, Portsmouth brothers Tuhin Shahensha, 27, and Mustakim Jaman, 22, were jailed for six years each after helping people travel to Syria to join the group. The siblings did not make the journey themselves in case they upset their mother. Around half of those who have travelled from the UK to Syria to join ISIS are believed to have since returned to this country. Advertisement

And they are being told to take care to target only ‘kuffars’ – unbelievers – and not to kill Muslims in any attack.

This could be a sign that ISIS leadership is concerned about its image following the Paris massacre, in which a number of Muslims were killed including the mother of a young girl.

The messages will also raise renewed concerns over the use of encrypted messaging services by terrorists – which are making it increasingly difficult for the authorities to monitor ISIS communications.

David Cameron has hinted that Islamic State – also known as ISIL – had changed tactics.

‘It is clear that the threat from ISIL is evolving,’ he said. ‘[The Paris] attacks suggest a new degree of planning and coordination and the greater ambition for mass casualty attacks.

'And we must recognize that however strong we are, however much we prepare, we in the UK face the same threat.’

Last month Andrew Parker, the Director General of MI5, admitted the security services’ ability to intercept communications was becoming more difficult.

And he said that plots against the UK were being directed from Syria.

Prime Minister: David Cameron (pictured earlier this week) has hinted that Islamic State had changed tactics

‘We are seeing plots against the UK directed by terrorists in Syria; enabled through contacts with terrorists in Syria; and inspired online by ISIL’s sophisticated exploitation of technology,’ he said.

‘It uses the full range of modern communications tools to spread its message of hate, and to inspire extremists, some in their teens, to conduct attacks in whatever way they can.

'The speed at which the process of radicalisation can occur online, and the emphasis on relatively low sophistication but nevertheless potentially deadly plots, are two major challenges.

‘On top of that, we have seen greater ambition for mass casualty attacks. All of this underlines the growing threat we face.’

TEEN BLOWS HIS £6K STUDENT LOAN ON FLIGHTS TO SYRIA TO JOIN ISIS Jailed for five years: Yahya Rashid (pictured in his mugshot), 19, blew his student loan to join ISIS By SOPHIE JANE EVANS FOR MAILONLINE A ‘street-smart’ teenager who conned his way into university and blew his £6,000 student loan on a trip to join ISIS was jailed earlier this week. Yahya Rashid, 19, used a forged BTEC certificate to gain a place at Middlesex University despite having an IQ of between 65 and 70 - far below the average of between 85 and 115. He then used a loan and educational grants that he was entitled to claim to take four friends from his mosque with him to the Turkey-Syria border via Morocco, Woolwich Crown Court heard. But while Rashid's friends crossed to border to Syria, the teenager, then only 18, backed out and remained in Turkey after talking to his father. He then returned to the UK and was arrested. Rashid was convicted of engaging in conduct in preparation for committing an act of terrorism, and engaging in conduct with the intention of assisting others to commit acts of terrorism. He had denied both terror charges. The teenager's trial heard that the group were stopped and questioned by police at Gatwick Airport as they left the UK but were subsequently allowed to board their flight to Casablanca. Rashid was able to outfox a suspicious police officer the airport when he arrived ‘out of breath’ at the departure gate with his pals Khalid Abdul-Rahman and Ibrahim Amouri, the court heard. PC Jane Duggan told the young men she was worried they might be on route to Iraq or Syria. However, they told the officer they were looking for love, not war. Sentencing Rashid to five years in prison on Wednesday, Judge Philip Katz QC told the teenager: ‘You lied under oath before the jury and they saw through your lies and evasion. ‘You were deceitful, insincere. 'Goodness knows what you would have gone on to do as a foot-soldier for ISIS.' Caught on camera: Rashid and his friends are seen walking through Gatwick Airport, headed to Morocco Advertisement
