British jihadist Sally Jones has been killed in a U.S. drone strike in Syria, Sky sources say.
Army colonel Ryan Dillon, a spokesman for the US-led coalition against IS, earlier tweeted that he "cannot confirm death of ISIS propagandist Sally Jones as a result of a coalition strike", in a message that was retweeted by the British government. There have been several such claims of IS militants having been killed only for them to resurface months later.
Jones left Kent in the United Kingdom, along with her son, to join Isis in 2013.
Her husband, Junaid Jussain, also an IS recruiter, was reportedly killed in a drone strike in 2015.
It is not known if her 12-year-old son, Jojo, who it is believed she had been using as a human shield against such aerial attacks, was also killed in the attack.
In an exclusive report in 2015, Sky News revealed the couple used online messaging services to urge British would-be recruits to carry out "lone wolf" attacks in the UK. She travelled to Syria with Joe "Jojo" Dixon, her youngest son from a previous relationship, later that year.
He said he would have preferred that Jones had faced trial, adding: "I represent a constituency that lost many people in 7/7 [the 2005 London bombings], and we remember what happened that day".
Major General Chip Chapman, the former MoD head of counter terror, said Jones would have been a "significant" target as a result of her alliance with Hussain and her role in recruiting IS fighters.
"If you take out those who are high value target women it is going to have an impact at the operation level of IS".
"Even if he got up to really bad things, he shouldn't have been targeted", he said. "We don't know for sure whether he was with her or not".
