Britain’s most wanted female terrorist Sally Jones, nicknamed the White Widow, has reportedly been killed in a drone strike.

The fugitive jihadi, who was once a punk rock singer, was said to have been killed in June in a US strike close to the border between Syria and Iraq.

For more than three years, Jones has been the world’s most wanted female terrorist and is now said to have become one of the list of infamous Britons to die after joining Islamic State of Iraq and the Levant (Isil).

She fled to Syria from Kent in 2013 to marry computer hacker Junaid Hussain, an Isil fighter from Birmingham, and took her then 11-year-old son, Joe “JoJo” Dixon, with her.

A Whitehall source told The Sun: “The Americans zapped her trying to get away from Raqqa. Quite frankly, it’s good riddance.”

CIA officials told their UK counterparts that a US Air Force Predator killed 50-year-old Jones in June, the newspaper reports.

The delay in her apparent death emerging is said to have been over fears her son might have also been killed in the strike. It is not known if her son was with her.

US intelligence chiefs said they cannot be 100 per cent certain that the strike killed Jones as there was no attempt to recover any of her DNA.

Jones had been a single mother of two living on benefits when she met her future husband, then 19, online and became besotted with him.

Hussain told Jones he wanted to leave to join Isil and encouraged her to join him.

Using the pseudonym Umm Hussain al-Britani, Jones is believed to have recruited dozens of women to the terror group by boasting on social media of how wonderful life was in the caliphate.
