A teenage girl plotted to launch a gun and grenade attack on the British Museum after her attempts to become a jihadi bride were thwarted, a court heard.

Safaa Boular was 17 when she allegedly decided to become a “martyr” after her fiance, an Islamic State militant, was killed in Syria.

She was so determined to attack London that she enlisted the help of her older sister after she was charged with planning to go to Syria, the Old Bailey heard on Thursday.

Rizlaine Boular, 21, had already admitted planning an attack in Westminster, that was allegedly to involve knives, with the alleged help of their mother, Mina Dich, 43, the jury was told.

Duncan Atkinson QC, prosecuting, told how Safaa Boular’s alleged plotting followed a failed attempt to marry the Isis member Naweed Hussain.

The couple declared their love for each other in August 2016, after three months of chatting on social media, the court heard.

Atkinson told jurors Boular wanted to join Hussain in Syria where they would carry out an attack. He said: “Their plan then was that together they would, as Hussain put it, depart the world holding hands and taking others with them in an act of terrorism.”

The court heard Rizlaine Boular had also tried to go to Syria two years before.

After Safaa Boular’s plan was uncovered, she allegedly switched her attention to Britain, keeping contact with Hussain through the encrypted messaging service Telegram.

The security services deployed specially trained officers to engage in online communication with them, jurors heard.

Atkinson said: “It was clear that Hussain had been planning an act of terrorism with Safaa Boular in which she could engage if she remained in this country. Both Hussain and Safaa Boular talked of a planned ambush involving grenades and/or firearms.”

She also told an officer posing as an Isis militant that all she needed was a “car and a knife to get what I want to achieve”, the court heard.

Atkinson said: “Based on her preparation and discussion, it appears she planned to launch an attack against members of the public selected largely at random in the environs of that cultural jewel and most popular of tourist attractions, the British Museum in central London.”

An attack would have caused at least widespread panic and was intended to cause injury and death, the court was told.

When she learned Hussain had been killed in April 2017, Boular’s determination was strengthened, the court heard. She was allegedly encouraged by her mother and sister to become a “martyr”.

But within days, she was charged with planning to go to Syria and was unable to carry out her “chilling intentions”, Atkinson told the court.

He said: “However, that those intentions were not just chilling but sincere and determined is demonstrated by the fact that she did not abandon them even when she was unable to put them into effect herself. Rather, she sought to encourage her sister Rizlaine to carry the torch forward in her stead.”

Atkinson told jurors that Rizlaine Boular, of Clerkenwell, central London, had admitted preparing acts of terrorism, which was apparently to be a knife attack in Westminster.

Safaa Boular, now 18, who lived at home with her mother in Vauxhall, south-west London, denies two counts of preparing acts of terrorism.



The trial continues.
