The American government has named Chatham's Sally Jones as a "specially designated global terrorist" on its Federal Register.

The move means Jones - a mum-of-two and recently a grandmother - is now the world's most wanted female terrorist and could be targeted in Syria by coalition airstrikes.

It was sanctioned by US secretary John Kerry, before the 46-year-old was added to a separate United Nations sanctions list, freezing her assets.

Sally Jones had previously said she wanted to return to the UK before she was killed.

Jones joined Islamic State in 2013, marrying Isis computer hacker Junaid Hussain and moving to Syria herself.

Hussain - the most prominent British member of Islamic State after the man known as "Jihadi John" - was then killed in a US airstrike in August.

A former guitarist with an all-girl rock band, she had previously moved from Chatham to Borough Green, where it is thought she was receiving grocery parcels from a church-organised food bank just weeks before moving to Syria.

Chatham mum Sally Jones was on a Pentagon kill list.

She has since posted pro-Isis statements from a series of Twitter accounts and encouraged Brits to carry out terror attacks.

The notice from the US Secretary of State on the Federal Register states: "I hereby determine that the individual known as Sally-Anne Frances Jones, also known as Sally Anne Jones, also known as Sally Jones, also known as Umm Hussain al-Britani, also known as Sakinah Hussain poses a significant risk of committing acts of terrorism that threaten the security of U.S.nationals or the national security, foreign policy, or economy of the United States."
