Both Rankine-Galloway and Corbyn were responding to a report Thursday by The Sun that cited Central Intelligence Agency officials in reporting Jones' death - by a drone strike in June near the Syria-Iraq border.
Unconfirmed reports suggest a housewife from Chatham who became one of Britain's most wanted Isis terrorists has been killed following a U.S. drone strike.
However, earlier this year it was reported that Jones had become disenchanted with life in Raqqa.
Jones, who was nicknamed the "White Widow", is believed to have publicized a list of American military personnel to be targeted by ISIS militants, led a group of female terrorists, and acted as a top recruiter online.
News of her death was not made public amid fears that her 12-year-old son Jojo may also have been killed, according to The Sun.
The Pentagon said it's looking into reports that a British Islamic State supporter known as the "White Widow" was killed by an airstrike this summer.
I guess that career didn't pan out for her, because she had converted to Islam, changed her name to Sakinah Hussain and moved to the Syrian Islamic State stronghold, Raqqa. Later, she became interested in music and played bass guitar in an all-girl punk band called Krunch.

Jones was very much a wanted figure; she rose up the Pentagon "kill list" in 2017 and was placed on a United Nations sanctions list, which included a freeze on assets, and was slapped with a travel ban.
