A British former punk musician who turned into an ISIS operative has reportedly been killed by a U.S. airstrike. Sally Jones, dubbed “The White Widow” by some in the press, was a member of the U.K. punk band Krunch before converting to Islam and traveling to Syria in 2013.

Jones played guitar and sang in Krunch, an all-girl punk band that experienced some success in the ‘90s. Long after her days onstage, she became one of the world’s most wanted female terrorists. She reportedly operated multiple Twitter handles, acting as a propagandist on social media. Jones spent much of her energy attempting to recruit women to join ISIS, providing practical advice on how to travel to Syria. She also encouraged individuals to carry out attacks in Britain, gave instructions on how to make homemade bombs and often shared pictures of herself posing with weapons.

Posts from Jones would often contain messages such as, “You Christians all need beheading with a nice blunt knife and stuck on the railings at Raqqa ... Come here I’ll do it for you.”

According to the Daily Mail, Jones was unemployed and “spent a lifetime on state benefits” before leaving for Syria. She went to join her husband and fellow Brit-turned-jihadist Junaid Hussain, who was killed in a U.S. drone strike in 2015.

Jones, along with her 12-year-old song Jojo, are both believed to be dead from a drone strike this year. The Pentagon was unable to confirm to The Guardian that Jones had been killed. Pentagon spokesman Maj Adrian Rankine-Galloway said, “I do not have any information that would substantiate that report but that could change and we are looking into this.” A separate Foreign Office spokeswoman added, “We do not comment on matters of national security.”
