An American jihadi bride living in a refugee camp after fleeing ISIS's last stand in Syria is begging the US to allow her to return home.

Hoda Muthana, 24, left Hoover, Alabama in 2014, in order to join ISIS in Syria, where she would later call for US Muslims to 'spill all of the blood' by launching terror attacks during Memorial Day events.

Now, having lost two of her three jihadi fighter husbands and living in a squalid refugee camp, she claims to have been brainwashed and made a 'big mistake' when she travelled to Syria.

Ms Muthana was 19 years old when she left the US and headed to Raqqa in Syria where she would first marry an Australian jihadist and then a Tunisian man. Both died fighting for ISIS, and she recently married a Syrian, The Guardian reveals.

During her time as a jihadi bride in ISIS's then-capital Raqqa in Syria, she would use social media to spread hatred against non-Muslims and call for terror attacks in the US.

In a 2015 tweet she wrote: 'You have much to do while you live under our greatest enemy, enough of your sleeping!

'Go on drive-bys and spill all of their blood, or rent a big truck and drive all over them. Veterans, Patriot, Memorial etc Day parades..go on drive by's + spill all of their blood or rent a big truck n drive all over them. Kill them.' [sic]

Now, she is living in the tent-city that is al-Hol - also known as al-Hawl - a refugee camp in northern Syria some 200 miles away from ISIS's 'last front' near the village of Baghouz by the Iraqi border.

Remorseful: Muthana, pictured in her high school year book in 2012, left the US to join ISIS in 2014 and as well as marry three jihadi fighters, she would go on to call for American Muslims to launch terror attacks on 'Veterans, Patriot, Memorial etc Day parades' [sic]

Muthana, pictured while in high school, says she 'deeply regrets' leaving the US, and that she believed she was doing what was right according to Islam because she had been brainwashed

Speaking to The Guardian, Ms Muthana claims she 'deeply regrets' leaving the US, and that she believed she was doing what was right according to Islam.

'I thought I was doing things correctly for the sake of God,' adding that she now believes she 'misunderstood' her faith.

'I was really young and ignorant and I was 19 when I decided to leave.'

At the time when she left, her family pleaded with her to come home and in an interview with BuzzFeed, her father said she had been 'brainwashed'.

The 24-year-old former University of Alabama student says she is worried about the future of her young child, a boy called Adam whose father is her second ISIS husband, and is begging the US and her family for forgiveness.

'I believe that America gives second chances. I want to return and I’ll never come back to the Middle East. America can take my passport and I wouldn’t mind.'

Ms Muthana is one of more than 25,000 displaced people who have turned up in al-Hol in recent weeks as US-backed forces closed in on ISIS's final sliver of territory in the Euphrates Valley, 200 miles away from the camp.

Another western ISIS bride living in the camp is 19-year-old Shamima Begum, who was just 15 when she and two classmates Kadiza Sultana and Amira Abase travelled from London's Bethnal Green to Syria in February 2015.

Begum, like Ms Muthana, is pleading with authorities to be allowed to return to her home country as she fears for the future of her son.

Conditions in the camp are better than on the road, but the makeshift tents, overcrowding and sparse resources pose a great health risk to children, with at least 29 dying in al-Hol in the past two months, mainly because of hypothermia, the World Health Organization (WHO) said earlier this month.
