The Islamic State group claimed responsibility Sunday for an attack by knife-wielding men who mowed down and stabbed revellers in London, killing seven people before being shot dead in a barrage of police gunfire.
Saturday night’s rampage at a popular nightlife hub around London Bridge by three men wearing fake suicide vests was the third deadly terror attack in Britain in less than three months and came only days before a general election.
“A detachment of fighters from Islamic State carried out London attacks yesterday,” said the Aamaq news agency, which is affiliated with the Islamic State group.
British Prime Minister Theresa May blamed “evil” Islamist ideology and vowed to crackdown on extremist content online worldwide, as police detained 11 people following two raids in east London.
National campaigning for Thursday’s vote was suspended for the day out of respect for the victims, who included 48 people treated in hospital for injuries.
Of those, 21 are still in a critical condition.
One Canadian national and one Frenchman were among the fatalities and seven French citizens were among the injured.
No details have been released about the perpetrators, who were shot dead within minutes by police.
Eight officers fired an “unprecedented” 50 rounds at the three attackers, according to Mark Rowley, head of national counter-terrorism policing, who said that a member of the public also suffered a gunshot wound.
Detectives were still investigating whether the assailants acted alone, and Rowley said their identities would be released “as soon as operationally possible”.
Police launched raids in the ethnically diverse London suburb of Barking in the hours after the rampage, arresting seven women and five men aged between 19 and 60 at two properties.
A 55-year-old man was later released.
May said the attack was driven by the same “evil ideology of Islamist extremism” behind last week’s Manchester suicide bombing that left 22 people dead, and the Westminster attack in March, which killed five.
“The recent attacks are not connected but we believe we are experiencing a new trend in the threat we face,” she said after chairing an emergency ministerial meeting.
She warned that perpetrators are inspired to attack “by copying one another”.
The assailants ran people over on London Bridge before lunging seemingly at random at the crowds gathered around Borough Market, which is full of restaurants and bars.
Gerard Vowls, 47, said he saw a woman repeatedly stabbed, and threw chairs, glasses and bottles at the attackers in a bid to stop them.
“They kept coming to try to stab me… they were stabbing everyone. Evil, evil people,” he told The Guardian newspaper.
Another witness called Eric told the BBC he had seen three men get out of the van and thought they were going to help tend those who had been run over.
Instead they “started kicking them, punching them and took out knives. It was a rampage really,” he said, adding that he heard a shout of: “This is for Allah”.
An Australian was among those hospitalised, while a Spaniard escaped with light injuries.
French Foreign Minister Jean-Yves Le Drian is due to visit Britain on Monday to speak to the injured French nationals, after President Emmanuel Macron said France was “more than ever at Britain’s side”.
Among those stabbed was a London Transport Police officer, who was one of the first responders on the scene and received injuries to his face.
A vigil for the victims will take place at nearby Tower Bridge on Monday evening.topics from
