'I'm glad she's dead': British ex-boyfriend of ISIS' 'White Widow' responds to claims she was killed by a US drone strike in Syria - and that their 12-year-old son may have died alongside her

The 12-year-old son of Britain's most wanted female terrorist is believed to have been killed alongside his mother in a US drone strike. Onetime punk rocker Sally Jones, from Kent, fled to Syria with her son JoJo in 2013 (pictured with his father Darren Dixon after his birth in 2004, left) before becoming a recruiter for the ISIS terror group. Earlier this year a friend said Jones, who went by the name of Umm Hussain Britaniyah, was desperate to return to the UK but was apparently being forced to stay by her husband's comrades, as well as her brainwashed son. JoJo had been used in sickening propaganda videos for the evil group. A nine-minute ISIS video issued last year appeared to show the boy executing a captured prisoner in a firing squad (right). It was claimed JoJo was refusing to leave the terror group having been brought to Syria by Jones and her toyboy lover and jihadi hacker Junaid Hussain in 2013.
