Two of the Britons, whose names were
among tens of thousands of militants on IS registration forms, were killed in
drone strikes.
Britons are among tens of thousands
of names on Islamic State registration forms that have been obtained by Sky
News.
Here is what we know about some of them:
The whereabouts of Abdel Bary are unknown
:: Abdel Bary
The 26-year-old man from London joined Islamic State in
2013 after visiting Libya, Egypt and Turkey.
He is designated as a fighter but is better known in the
UK as a rap artist. His whereabouts are unknown.
He was once thought to have been the masked militant
Jihadi John who appeared in a number of videos of foreign hostages being
killed.
But Jihadi John was later revealed to be Mohamed Emwazi.
According to reports last July, Bary left IS and went on
the run in Turkey.
It was unclear why he had apparently has fallen out with
IS.
But he was reportedly among a number of disillusioned
Westerners to have quit the jihadist group following coalition airstrikes.
Bary was reported to have disguised himself as a refugee
and escaped as IS fled Tal Abyad near the Turkey-Syria border last June.
Reyaad Khan was killed in an RAF drone strike
:: Reyaad Khan
The 21-year-old from Cardiff was killed in an RAF drone strike on 21 August,
2015.
He was said to be part of a jihadi internet warfare cell
and presented a "clear and present danger" as he was the target of
the strike.
He is believed to have travelled to Syria in late 2013.
Khan appeared in an IS video in June 2014, wearing a
headscarf and armed with a Kalashnikov assault rifle, and called for Westerners
to fight in Iraq and Syria.
Junaid Hussain was killed by a US drone strike
:: Junaid Hussain
Hussain was killed by a US drone strike on 24 August, 2015,
near Raqqa, the "Caliphate's" capital in Syria.
The 21-year-old hacker-turned-jihadist from Birmingham
ran the IS information and recruitment arm from Syria.
He was identified by the US Secret Service as a top-five
target for elimination by drone strike.
Hussain and Khan were thought to have been actively
involved in orchestrating a number of plots to attack high-profile public
commemorations.
One of the planned attacks, uncovered by a Sky News
investigation, was aimed at August’s VJ Day celebrations in London.
Hussain's widow is militant Sally Jones
Hussain's widow is 46-year-old Sally Jones from
Birmingham.
A former punk from Chatham, Kent, she travelled to Syria
with her husband and has been actively dealing with female IS-supporting
jihadists.
She uses her Twitter account to recruit women to the
terrorist organisation and has provided practical advice on how to travel to
Syria.
