AN Islamic State recruiter dubbed “Mrs Terror” is feared to have slipped into Britain - and may be heading for Scotland with two young jihadis in tow.

Special Branch officers are on full alert at Scottish airports as they look out for Muslim convert Sally Jones, known as Umm Hussain.

Police in Scotland have been warned that Jones - dubbed ‘Mrs Terror’ originally from Kent - has reportedly been seen in Birmingham with an 18-year-old and a 22-year-old.

The gender of her companions is unclear.

Officers have been told she is to be treated as “hostile”.

The dramatic news comes after unemployed mother-of-two Jones - who was believed to have been based in Syria with her husband former computer hacker Junaid Hussain - revealed to undercover investigators that she has a female terrorist in Glasgow ready to launch a devastating attack at Saturday’s VJ commemorations.

A source said: “This is worrying but Special Branch officers are working on this to track her down. Officers are in place at various airports such as Glasgow, Prestwick and Aberdeen to keep an eye out for her.

“There is intelligence that she was last seen in Birmingham with two individuals aged 18 and 22. Detectives are also keeping an eye on shopping centres and large events.”

This week, Jones and Junaid Hussain told undercover reporters posing as wannabe jihadis to carry out so-called ‘Lone Wolf’ attacks in Britain and even sent them bomb-making guidebooks.

The militants also revealed that the Queen and the Royal Family would be targeted with pressure cooker bombs at this Saturday’s VJ commemorations.

Another terror chief has meanwhile claimed that four or five British recruits who trained in Syria have now returned to Britain to launch strikes.

Sky News reporters posing as male and female jihadis on Twitter and in chatrooms contacted the two British ISIS militants – Hussain, a 21-year-old from Birmingham, and Jones, a former punk from Chatham in Kent.

Hussain runs the ISIS recruitment arm in the terror group’s de facto capital of Raqqa in Syria and is a top-five target for the U.S. Secret Service. Jones was thought to be working alongside her husband in Raqqa recruiting female militants.

In a series of conversations on encrypted messaging sites over a four months, the reporters convinced Jones that they wanted to make a bomb.

Jones then gave detailed instructions on how to construct a pressure cooker explosive and insisted on seeing receipts to prove they had bought the materials.

She revealed she had another potential bomber in Scotland and two others who had so far failed to carry out attacks and urged the undercover reporters to start a gang themselves.

She later sent details of the plot to attack the Royal family at the VJ commemorations on Saturday, which were passed on to the Metropolitan Police’s anti-terror branch.

On Tuesday, the Metropolitan Police’s Specialist Operations unit issued a statement saying: “The police have for some time recognised, and spoken about, the fact that the fight against terrorism has a number of challenges; the real threat from people returning as trained terrorists from Syria and Iraq; the equal threat of those who have not travelled being encouraged and incited to commit attacks in the UK and the young and vulnerable being enticed out to Syria through internet based grooming.

“The police, together with our security partners, remain alert to terrorist threats that may manifest here or where individuals overseas may seek to direct or inspire others to commit attacks in and against the UK.

“It is always helpful when journalists share with us information, as Sky did in this case, that could indicate terrorist or criminal activity and we will investigate and take action where appropriate.

“The UK threat level from international terrorism remains severe. We would like to reassure the public that we constantly review security plans for public events, taking into account specific intelligence and the wider threat.

The Mail on Sunday revealed at the weekend that a specific threat was made against the Queen, triggering an urgent review of security arrangements for the weekend’s events.

ISIS recently released a sickening video showing their latest appalling execution technique - forcing men to kneel on explosives and then blowing them up.

Police Scotland issued the following statement after we asked about fears that Umm Hussain was in the UK and heading to Scotland.

ACC Ruaraidh Nicolson, Organised Crime, Counter Terrorism and Safer Communities, said: “Police Scotland is working with The Metropolitan Police following media reporting about potential terrorist activity in the United Kingdom.

“The threat level in the UK remains at Severe which means an attack is highly likely.

“Against that backdrop Police Scotland constantly assesses and reviews its response to the threat from terrorism with Policing operations being shaped appropriately and based on the latest intelligence analysis.

“The latest media reporting has been included within our day to day considerations. I would like to reassure the public that we are working closely with our security partners and we remain alert to all terrorist threats that may manifest here or where individuals overseas may seek to direct or inspire others to commit attacks in and against the UK.

“I would ask that communities remain alert for any suspicious activity and report it to the police so we can take the appropriate action required.

“Through the excellent relationship we have with the diverse communities across the country, Police Scotland and our partners remain committed to reducing the risk associated with people becoming involved in, or supporting terrorist or extremist behaviour.

“Communities are our biggest ally in the threat against terrorism.”
