ONE day after the murders of scores of innocent people by Islamic terrorists in Tunisia, France and Kuwait, a former public school girl from the suburbs of Glasgow, wrote words that were almost unthinkable.

She called the killings: "A day that will go down in history. Revenge".

Aqsa Mahmood, is now 21. She left Glasgow in November 2013 and married a terrorist fighting for Islamic State - which the Sunday Herald is now referencing as Daesh. Her blog - under the name the nom de guerre Umm Layth - provides a chilling insight into her journey from being an average Scottish teenager to becoming a 'Jihadi bride'.

Started in 2013, at first it is a mixture of videos, pictures and quotes highlighting the conflict in Syria and praising Daesh, peppered with references about her family and day to day life, such as a love of Disney films.

Less than two years on, after travelling to Syria, Mahmood - who is thought to have been radicalised through the internet - is posting hate-filled messages warning Western leaders that "kuffars"- a derogatory term used to describe non-Muslims - will be destroyed. Ironically, she often misspells 'Allah' as 'Allaah'. We have left her spelling mistakes uncorrected.

FAMILY AND HOME LIFE

At the beginning, Mahmood appears to hold at least some tolerant views. In one of the very first postings in the blog, on January 22 2013 she described wearing a hijab as "fardh" [a religious duty] but added: "However I absolutely hate to see sisters think just because THEY wear it and another sister doesn't it automatically gives them the right to judge them? And look down upon them? Of course not."

Mahmood makes several affectionate references to her family life. On February 4 2013 she wrote: "Lol my sister just said that 'I'm going to eat so much of that cake that Mum's gonna regret making it.'"

On March 31, she wrote. "My plan for today is to watch all the Lion Kings. Doesn't get as productive as this."

On April 9 2013 she wrote about spending time with her sisters. "I always say I'm going to be productive but here I am again sat in front of the TV watching some Disney film with my little sisters."

On the May 8 2013, there is a flicker of something darker, when she says it doesn't affect her when people call her an extremist, fundamentalist or too religious. Though she adds: "When my family also think the same then it does upset me."

Come February 28 2013, Mahmood talked of her excitement at buying her first abaya - a traditional cloak - adding: "Lolz mums gonna freak once she finds out how much money I have spent on online shopping this week."

The blog posts also hint at a studious - but reclusive - personality. On the March 8 2013 she posted: "My dad asked me if everything is alright, my family think I'm weird because I prefer my own company and being alone. Lol. All I need in this life is me and my books."

There is also a hint of the desire for fame, she has courted since she fled to Syria. On April 19, she says: "I get more attention on twitter [than her tumblr blog]. I don't feel famous on this. But then I complain that I don't like the attention?!?"

A big preoccupation Mahmood has at this stage is not plucking her eyebrows - which she believes is 'haram' or not permitted by Islamic law. On April 20 2013 she wrote: "In this day and age plucking your eyebrows is the norm and many are not even aware of how big a sin it is. Allaah curses those who pluck their eyebrows".

Later on August 7, she wrote a post about "the struggle when your mum and sister try and convince you to get your eyebrows done", adding: "This is my jihad for now...Looool."

DESCENT INTO RADICALISATION

On April 6 2013, one blog follower asks her to reveal her 'revert' story - or how she became interested in Islam. Her response suggests it was an incident in 2008, when an Iraqi journalist threw two shoes at US President George Bush as a sign of contempt.

Mahmood wrote: "I was watching TV and I saw this man throw a shoe at Bush and it inspired me to look into such an amazing religion. May Allaah reward the brother who's shoe was aimed for that dogs face."

But other postings in the run-up to leaving for Syria reveal the extremist views she holds. A number of derogatory references are made about Shia Muslims - Daesh militants are Sunni and have carried out atrocities against Shias, including the deadly suicide bomb attack on a Shia mosque in Kuwait last week, which killed 27 people and injured more than 200.

On May 15 2013 one blog follower challenged Mahmood on her views saying: "Some of the stuff on your page is really offensive, I hope that you meet a Shia and realise that behind the labels, we're all just human beings who need to turn to Allah."

But in response she wrote: "May He guide you as I can tell you are a Shia, really pity you I really do...Stop tarnishing Islam with that filthy sect."

She also writes posts praising Daesh fighters, including one on the April 3 2013 which said: "We are proud of them...They are the Lions of Jihad."

In March 2013, posts hint that Mahmood - who was studying radiography at Glasgow Caledonian University - is in turmoil at the direction her life was heading. She wrote: "My current self is constantly at war with my former-self. The two are fighting for control of my future-self."

And on March 20 2013, she said: "I feel like I have no direction in life anymore. It's funny how things work out, once upon a time I used to be such a career obsessed girl. Now I have no clue. I just want another fresh start and to do it right this time."

On the October 10 2013 a post simply read: "I don't belong here" and later that month, she writes of feeling "so so Halal jealous" hearing of all those who have made it to Syria.

Mahmood travelled to Syria through Turkey in November that year.

LIFE IN SYRIA

According to the blog, Mahmood made it to Syria by November 30 2013. Mahmood does not update her blog again much until March, when the posts include pictures of the cities of Raqqa and Aleppo in Syria.

On April 9 2014 she wrote a poem dedicated to her mother. It included the lines: "Four months have passed since I last saw your face...four months have passed since I departed without a goodbye."

In it she appears to express regret at leaving her mother, saying she begs and cry to Allah every night "to unite us again" and asks for forgiveness.

But she also told her mother she has "raised a Lioness among a land of cowards" and that "this world is not worth it at all". It ends with the line: "I know you've accepted that I'm never coming back".

On the same day, she begins the first of a series of entries aimed at other female recruits to Daesh posted under the title of "Diary of a Muhajirah" [meaning one who has made the journey to Syria]. In the first entry, she said she wants to "paint a realistic picture of what life is like for the sisters here" - and reveals she married three months earlier.

The posting contained advice on everything from bringing clothes, shoes and makeup from the west to a rundown on what jihad is like for "sisters". She explained that women do not take part in any fighting, but their duties revolve around cooking and cleaning, as well as looking after and educating children. Chillingly she also said the role of women is important to raise the next generation of Daesh fighters. She wrote: "How can you not want to leave behind offspring who may by the will of Allah be a part of the great Islamic revival?"

In a second diary entry, posted in June 2014, Mahmood talks of the difficulties in leaving family behind. She wrote: "The first phone call you make once you cross the borders is one of the most difficult things you will ever have to do...when you hear them sob and beg like crazy on the phone for you to come back it's so hard."

She added: "But as long as you are firm and you know that this is all for the sake of Allah then nothing can shake you. Many people are using their parents as an excuse to stay back from making their feet dusty and would rather live in dishonour amongst the kuffar."

JIHAD AND WAR ON THE WEST

In a diary entry in September last year Mahmood claimed most women she has met who have joined Daesh have similar backgrounds to her - previously studying at university with big happy families, who could have been blessed with "a relaxing and comfortable life and lots of money."

Hinting that she is profiting from Daesh atrocities, she said that there are rewards in the form of "ghanimah" - a term used to describe spoils of war. "Know that honestly there is something so pleasurable to know that what you have has been taken off from the Kuffar," she wrote. "Some of the many things include kitchen appliances from fridges, cookers, ovens, microwaves, milkshake machines...and most importantly a house with free electricity and water provided to you due to the Khilafah [Islamic state] and no rent included."

In this post she also wrote of being "free of those living in the West" - and issued a chilling warning to UK Prime Minister David Cameron and US President Barack Obama that their countries "will be beneath our feet" and people destroyed.

She added: "If not you then your grandchildren or their grandchildren. But worry not, somewhere along the line your blood will be spilled by our cubs...This Islamic Empire shall be known and feared world wide."

Mahmood also told her followers: "This is a war against Islam and it is know that either "you're with them or with us". So pick a side..."

Her blog has been less active this year, but a diary entry in January 2015 referenced the "hefty reality" that those who marry Daesh fighters have to prepare for their husband's deaths.

One of the last posts to date this year was a badly written hate-filled poem about the recent atrocities in Tunisia, Kuwait and France. It read: "Revenge. This is an answer to our imprisonment, they try to make us deaf, dumb and blind to the light of Allaah, but it will always outshine.

"Kuwait, France and Tunisia is where they reside. They left a mark which will always remain. Permanent and blunt."

Mahmood - once a studious young woman, destined for career helping others - ended with the line: "If you show no mercy with us then why should we with you?"
