Jones was killed close to the border between Syria and Iraq by a US Air Force strike in June, according to The Sun.
She and her husband Junaid Hussain went to Syria in 2013 to join Isis in 2013.
Hussain was killed by a US drone in 2015. He is thought to have been planning “barbaric attacks against the West”, including terror plots targeting “high profile public commemorations” that summer.
News of her death was not made public amid fears that her 12-year-old son JoJo may also have been killed.
Who was Sally Jones?
Mum-of-two Jones, 50, was born in Greenwich, London.
She moved to Chatham in Kent where it is thought she worked as a perfume saleswoman for L’Oreal. She is also known to have been a punk rocker in a band called Krunch.
She became known as ‘Mrs Terror’ after marrying Junaid Hussain, who was in charge of recruiting new hackers to Isis, before the pair fled to Syria in 2013.
She took her son from a previous relationship with her, while her 20-year-old son remain in the UK.

Why was she so wanted by the US?
Jones is accused of being one of the most prolific planners in terror attacks. It is claimed she was one of those behind a failed plot to kidnap and film the beheading of a US army vet.
US authorities believe she and her husband were behind at least a dozen Isis terror plots, including a plot to target the Queen during VJ Day celebrations in 2015.
She used her Twitter account to recruit women and provided practical advice on how to travel to Syria.
What about her 12-year-old son?
Jones is said to have used her young son, JoJo, as a human shield to protect herself whenever she went outside. His father said Jones brainwashed the boy, who was reportedly forced to execute Isis prisoners.
He was renamed Hamza and has been seen in Isis videos. He would not have been deliberately targeted in the attack due to his age and may have been killed accidentally.
A return to Britain?
Jones, who was also known as Umma Hussain al Britani, was reportedly desperate to flee the Kurdish refugee camp in Syria where she lived and return to Britain.
Her friend Aisha told Sky News: “She was crying and wants to get back to Britain but Isis is preventing her because she is now a military wife.” Thousands of Brits signed a petition to block Jones from ever returning to the UK.
How was she killed?
Jones was reportedly killed by the CIA in a drone strike close to the border between Syria and Iraq. News of her death was kept from the public as the US were not sure if her son was also killed.
Her death has not been 100% confirmed due to a lack of DNA evidence. A Foreign Office spokeswoman said: “We do not comment on matters of national security.”
