A middle-aged punk rocker dubbed 'Mrs Terror' when she fled the UK to join ISIS has tweeted chilling messages of pride after her British ISIS fanatic was killed in an American drone strike.

Mother-of-two Sally Jones, 45, took to Twitter overnight to say she 'will never love anyone' other than computer hacker and foreign jihadi recruiter Junaid Hussain, 21.

She added that she was 'proud' that her husband was killed by 'the biggest enemy of Allah' and dubbed the anti-ISIS coalition as 'Crusaders' for carrying out airstrikes on the terror group.

Hussain, who was originally from Birmingham, died last month after a U.S. drone struck the car he was travelling in through ISIS' de facto capital city Raqqa. He was widely reported as number three on America's ISIS target list due to his hacking credentials and key role in recruiting foreign fighters.

Calling herself Umm Hussain Britaniya, Jones took to Twitter last night to post a series of messages praising Hussain before her account was suspended.

'I'm proud my husband was killed by the biggest enemy of Allah, may Allah be pleased with him, and I will never love anyone but him,' she wrote.

Referencing ISIS jihadis' belief that their fighters become martyrs and are richly rewarded in heaven when they die, she added: 'The Crusaders think they win when they kill us. They don't we win.'

Although her account was only active for a matter of hours, ISIS supporters quickly began following her and retweeting her posts, with some even making direct contact with her.

In response to another jihadi widow, Jones said: 'Yes uhkty [sister] may Allah accept your husband too into the highest ranks of jannah [heaven] and jzk [may Allah reward you] for being here for me.'

Muslim convert Sally Jones fled her home in Chatham, Kent in 2013, taking her 10-year-old son with her

Jones is a 45-year-old former punk band guitarist who has spent her life on benefits. Her toyboy husband Junaid Hussain, 21, is an ex-computer hacker from Birmingham who she met online.

The Muslim convert fled her home in Chatham, Kent in 2013, taking her 10-year-old son with her.

In recent years, Jones had become sucked into a fantasy online world, adopting alternate personas and calling herself Skya and Catgel. She also contributed to forums on conspiracy theories, witchcraft and black magic.

Hussain was meanwhile the leader of a shadowy computer hacking group known as Team Poison, which had claimed responsibility for hacking attacks on politicians, businesses and a humanitarian agency.

He was jailed in 2012 for stealing personal information from Tony Blair and publishing it online. He also admitted making hoax calls to the Metropolitan Police anti-terrorist hotline.

After the pair starting exchanging messages online, Jones seems to have become radicalised and later claimed Britain and America were 'terrorist' nations.

A million miles from her previous life: In the early 1990s Sally Jones was the lead guitarist in an all-girl rock band called Krunch who played a series of gigs in the South East

It is unknown whether the couple travelled to Syria together, but Jones at least is thought to have sneaked into ISIS-held territory at the end of 2013.

She later posted a message online claiming she wanted to behead Christians with a 'blunt knife'.

Hussain was killed on August 24 when a US drone struck the car he was travelling in through ISIS' de facto capital Raqqa in northern Syria.

An anonymous senior US official told CNN: 'We have a high level of confidence he was killed. There is a good deal of sensitivity because Hussain was a British citizen targeted by the US.'

His death was later confirmed by David Cameron during a Commons statement in which he announced the death of two other British nationals following targeted RAF drone strikes.

The Prime Minister revealed that Cardiff-born militant Reyaad Khan, 21, was killed by an RAF drone strike alongside another British fighter Ruhul Amin in Raqqa on August 21.

Three days later the U.S. drone killed Hussain.

Later it emerged that ISIS' British executioner-in-chief Mohammed Emwazi, better known as Jihadi John, tops a government 'kill list' of up to a dozen British radicals whom ministers want taken out with targeted drone strikes

Leader: The mother-of-two, who slipped into Syria at the end of 2013 with her 10-year-old son, is seen punching her hand in the air and shouting Arabic chants, which are then echoed by her fellow militants

Jones' role in ISIS is a million miles from her former life in the Medway towns.

In the early 1990s she was the lead guitarist in an all-girl rock band called Krunch who played a series of gigs in the South East.

A clip of one of her performances posted online shows her with a shock of blonde hair and wearing a leather mini-skirt.

In recent years she developed an interest in art, attempting to sell fantasy pictures as well as T-shirts, mugs and key rings through a niche website.

Last year, her brother Patrick, 52, who runs his own paving company, said his family were deeply shocked by her conversion to radical Islam.
