London: The UK's elite military unit Special Air Service will be sent to Syria with a hit-list of 20 top high-value ISIS targets, including a British woman dubbed as 'Mrs Terror', according to a media report.
The kill mission is part of renewed efforts to eliminate Islamic State commanders in Syria and will happen regardless of the outcome of Wednesday's vote in parliament, the Daily Express reported.
Sally Jones, a mother of two from Kent, who has made herself invaluable to the Islamic State of Iraq and Syria (ISIS) is believed to be among the targets.
Jones' husband Junaid Hussain was killed in a drone strike in the ISIS "capital" of Raqqa, Syria ? the same city where the US also caught up with "Jihadi John" ? in August.
Other moves against ISIS will include deploying of Britain's most sophisticated nuclear submarine into the eastern Mediterranean, armed and ready to launch a Tomahawk cruise missile strike on the Islamic State's Raqqa power base, the report said.
Around 40 members of the SAS are already supporting US Special Forces in Syria but that number is to be doubled after defence chiefs ordered the head of Britain's special forces to focus all efforts against ISIS jihadis in Iraq and Syria.
Though the force will take part in a range of missions, its main task will be to target key British extremists.
While the names on the kill list remain secret, they are believed to include Jones, from Chatham, Kent, who converted to Islam and uses the name Sakinah Hussain.
A vital part of ISIS' recruiting machine, she has vowed to behead Christians.
According to intelligence sources, her links with the UK make her a "live threat" to national security.
In total 10 Britons are believed to be on the list, including British brothers Nasser and Aseel Muthana, aged 20 and 17.
They left for Syria last year and are believed to have been close associates of the two Britons killed in the August drone strike. In all, more than 700 British nationals have left the UK to join ISIS.
"The SAS will use the same strategy in Syria that it used in Afghanistan, when they effectively destroyed the Taliban?s middle order," a senior military source was quoted as saying.
The kill list was created from intelligence supplied by GCHQ, the government's eavesdropping service, and the US National Security Agency.
Both organisations have spent the past two years monitoring phone calls and internet activity between terrorists.
British Special Forces have already formed a series of "hunter-killer" teams with US counterparts, including Delta Force and Seal Team 6.
