One of the three East London schoolgirls who fled the UK to become 'jihadi brides' in Syria, has been tweeting images of her new life in Islamic State.

Shamima Begum, 15, Kadiza Sultana, 16, and Amira Abase, 15, flew to Istanbul from Gatwick Airport last month, crossing into Syria.

Confirming fears that the teenagers had joined the Islamist militants, two months after leaving her home in East London, the British schoolgirl posted a picture of herself enjoying dinner with another Jihadi bride.

Posting a public tweet of her takeaway meal, including fried chicken, chips, pizza and a kebab, the radicalised teenager offers a rare insight into the life of the British runaways.

Tweeting under the name Bintt Abbas she added the caption "dawla takeaway w/ @um_ayoub12'." The world 'dawla' is another name for Isis.

Her dinner companion was a 16-year-old muhajirah, who is believed to be part of another group of radicalised western teenagers who have travelled from Europe to join Isis.

Earlier in the year, the young bride tweeted the chilling message "uh wanna behead some kafirs [non-Muslims] now".

Before her departure to Syria, Abase tweeted a picture of herself with Shamima Begum and Kadiza Sultana, before their departure. The picture, captioned 'Akhwaat', meaning 'sisters' in Arabic, shows the three school friends sitting in a London park, looking much like any ordinary teenagers.

Many of her messages allude to her Islamic faith, and earlier tweets from before she left for Syria present an image of a normal teenager and her everyday life in East London including photos of her building a tower with neon highlighter pens; photos of tiger cubs and pictures of the London skyline, taken from her family home. She tweets about her love for Vans and Nike trainers and reveals she was a Chelsea fan and had a liking for Cookies and Cream waffle desserts, revealing habits and interests typical of young teens. The innocent tweets give no indication of what was to come and what she and her friends had been planning.

Earlier this week, it was reported that Abase and her two classmates had joined the group of British female jihadis who run Isis's ultra-religious police force and are now training with one of the notorious female arms of Isis.

Shamima Begum is believed to have forged social media links with three of the British leaders of the al-Khansa brigade, an all-women militia set up by the terror group a year ago.

The much-feared group are known for their brutality and are seen on the streets of Raqqa, dressed in black and wielding automatic weapons as they patrol the streets, spying on citizens and ever-ready to carry out brutal assaults on anyone failing to abide by the laws of the terror group.

The schoolgirls anxious parents an emotional joint statement on Mother's Day, pleading for their daughter's to return home.

The trio left their homes in east London after telling their families they would be out for the day.
