Safaa Boular, 18, is accused of plotting to launch ISIS-inspired terror attacks in Britain

A teenage girl accused of plotting to launch ISIS-inspired terror attacks at London landmarks fantasised about killing Barack Obama in online chats with her jihadi fiancé, a court heard today.

Safaa Boular, 18, was arrested as she planned a suicide attack on the British Museum using guns and grenades after being trained online by Naweed Hussain, a British Pakistani who joined Islamic State in Syria in June 2015, it is claimed.

Hussain sent her images of a personalised Kalashnikov assault rifle he dubbed 'our klash', bragging it was '1 of a kind', along with two grenades and a handgun.

When her ploy to travel to Syria and marry Hussain - with whom she bonded over a mutual love of TV game show Deal Or No Deal - was thwarted last April, she urged her older sister, Rizlaine, 22, to 'carry the torch forward' in her place, it is alleged.

Rizlaine and her mother, Mina Dich, 43, went on a reconnaissance trip scouting major landmarks around Westminster, the Old Bailey heard.

The pair purchased a packet of knives and a rucksack on April 26 in preparation for an attack near the Palace of Westminster codenamed the 'Mad Hatter's Tea Party', it is claimed.

Today, jurors were taken through downloads from one of the phones seized from Boular when she returned to the UK from a holiday in Morocco in August 2016.

Anti-terror police were able to see that the teenager installed chat applications like WhatsApp and the encrypted Telegram along with anti-spy applications to guard against surveillance.

Images uncovered on the device included a child wearing a headband bearing the IS logo wearing a suicide vest and holding a gun, a black glove with the same logo making the terror group's upward-pointing salute and others depicting the beheadings of men clad in orange jumpsuits synonymous with the organisation.

On 16 August, Boular and Hussain talked about getting married, having twins and the money he was sending to her sister Rizlaine in order to bankroll her travel to Syria.

'U wil b getting a lot of money insha'Allah*..' he pledged, adding: 'U sister is jus receiving envelope afta envelope.'

Whilst discussing her living in a safe house when she arrived, Hussain warned her 'belts are a must', referring to wearing a suicide belt to use if threatened by non-believers.

'Don't eva b hesitant 2 pull da pin ok,' he instructed. 'Ur honour is worth more than any kaafirs life.'

Boular then asked if 'the pin make me go' followed by an image of an explosion.

Hussain replied 'yes straight away' before counting down from five and laughing.

'When ur teaching me how to use it in sha Allah Don't actually pull the pin k,' the teenager joked back.

Reassuring her that it would be 'very easy', Hussain told her they would 'depart 2 world holdin hands' and take others with them in a terror attack.

The teenager asked 'is it us' versus an image of former US president Mr Obama, prompting Hussain to call him a 'filthy kalb', or dog.

Referring to the former President, he asked her: 'How will y kill him. If u had da choice.'

Boular claimed she would 'shake my hand with Mr president' accompanied by two images of explosions.

They went on to talk about the possibility of dying together as martyrs for their joint cause. Boular told Hussain she wanted to reach paradise through death 'so bad'.

The jihadi promised the pair would 'go forth one day' or she would 'fulfil her role' as a martyr and a wife who would 'raise lions'.

Jurors heard the couple bonded over their mutual love of TV gameshows including Deal Or No Deal and The Chase.

During a Telegram conversation two days later, on 18 August, their discussions included what were doing, what they were eating and even setting Rizlaine up with a husband.

In one exchange, the topic turned to the classic Channel 4 gameshow, prompting Hussain to declare it was 'a sik game'.

He told Boular his 'mum's rule' in the house was 'Deal Or No Deal followed by The Chase' and laughed.

'My mum loves The Chase,' replied Boular, in reference to Dich, who has admitted assisting her sister Rizlaine in preparing for a knife attack around the Palace of Westminster.

'I remember I used to watch some celebrity couples show. I can't remember the name. Then straight after we'd watch Family Fortunes.'

In other messages, Hussain sent a heart emoji to tell her he loved her, told his 'princess' Boular she was 'shexy' and sent smiley face emojis with love heart eyes.

The teenager told him 'I love you too', jurors heard.

Hussain also sent an image of him and an executed 'spy' who had been 'stabbed in da heart'. Boular later joked: 'U Daesh Are psychos.'

Boular, of Lambeth, South London, denies two counts of engaging in preparation for terrorist acts.

Her sister Rizlaine, of Clerkenwell, Central London, has already admitted planning an attack in Westminster, allegedly involving knives and with the help and support of their mother, Dich. The trial continues.
