A female jihadist from Britain has said she wants "David Cameron's head on a spike," as she laughed off the Prime Minister's new laws to counter terrorism in the UK.
It is believed the unnamed 18-year-old, who is prolific Twitter user and goes by the Twitter handle @UmmKhattab, is based in Raqqa, north-east Syria.
Raqqa, an Islamic State (IS) stronghold which is the town closest to where US journalist James Foley was beheaded, has been identified by experts as a hotspot for young British girls who have travelled to join extremist fighters.
In a collection of hate-filled tweets, the young girl threatened the PM for "waging war" on IS.
In sha Allah a day will come when David Camerons head will be on a spike as he continues to wage war on the awilya of Allah— Al jazraweeya (@UmmKhattab__) September 7, 2014
As the terrorist threat to the UK was raised from substantial to severe, the prime minister said last month that legislation would be introduced so it was easier to seize jihadists' passports.
But responding to Cameron's new laws to crack down on terror suspects, the teenager said plans to block passports was "laughable", adding "like we care lol".
I really do not understand why Britain is threatening to remove our citizenship like we care lool its actually quiet laughable— Al jazraweeya (@UmmKhattab__) September 7, 2014
Her latest threats against the UK came as it was revealed that British female jihadists are behind an ultra-religious all female militia in Raqqa that is brutally punishing "un-Islamic behaviour" in the area, according to the Sunday Telegraph.
In her violent anti-UK rhetoric, the girl has also spoken with excitement of plans to raise the black flag of IS over Downing Street and said that leaving Britain is "the best thing I've done in my 18 years."
The black flag is not only limited to iraq and shaam in sha Allah it shall fly over 10 downing st— Al jazraweeya (@UmmKhattab__) July 10, 2014
I might be only 18 but I know coming to shaam the best decision staying in the UK completely diminishes your islam— Al jazraweeya (@UmmKhattab__) September 8, 2014
Best thing ive done in my 18 years in this world is come to the blessed land of shaam and leave Britain the land of kuffar— Al jazraweeya (@UmmKhattab__) August 14, 2014
She has also spoken of her friendship with Aqsa Mahmood, the Irn-Bru loving Scottish woman who travelled to Syria and married an IS fighter.
Umm Layth was a prolific tweeter until she was identified in the press as the 20-year-old Glaswegian.
In her tweets, she urged Muslim men and women who could not come to fight to instead commit terrorist atrocities at home, praising the brutal murder of Drummer Lee Rigby in Woolwich, the bombing of the Boston Marathon and the shooting of soldiers at Fort Hood in Texas. "If you cannot make it to the battlefield, then bring the battlefield to yourself," she tweeted.
Me and @UmmLayth_ are so funny I think its a British thing no one else gets our banter in the house— Al jazraweeya (@UmmKhattab__) August 14, 2014
But both of the girls' Twitter pages are littered with tweets that betray their Westernised roots.
One from Mahmood asks for someone to "make a Hijrah [pilgrimage] from Scotland already and bring me Irn-Bru.” She also tweeted with delight at receiving European food, including Pringles crisps and Nutella.
UmmKhattab, meanwhile, has tweeted her love of sunsets.
The sunset in shaam is always so beautiful— Al jazraweeya (@UmmKhattab__) August 10, 2014
Experts have warned that women are the new target for recruitment for the Islamic State (IS), with researchers seeing "unprecedented" calls for fighters to marry British and European women.
The women, most of whom are just teenagers, are bombarding IS fighters with marriage proposals during social media 'Q&As' and researchers estimate as many as 50, most of them British, could have already gone to join fighters in Syria and Iraq.
"Typically, the women who are out there tend to form clusters, they might be married to Isis fighters in the same unit," said Melanie Smith, a research associate at the International Centre for the Study of Radicalisation (ICSR), King's College, who monitors the recruitment of women by IS told The Huffington Post UK.
The ICSR has warned that many more young women have been making inquiries about travelling to Iraq and Syria in the weeks since the beheading of Foley.
"There's been specific calls for doctors, engineers, lawyers to come to the 'Caliphate', and for a state to function, women need to come, they need to have children", Shiraz Maher, Senior Fellow at the ICSR told The Huffington Post UK.
Four women from the UK, including Mahmood and Umm Khattab, have so far been identified by experts.
