12 people arrested after London terror attack

Twelve people were arrested in counterterrorism raids in the town of Barking east of London, police said on Sunday. Seven women aged between 19 and 60 years of age and five men aged 28 to 55 were arrested. One of the men was later released. Police said in a statement that “a number of addresses” continue to be searched.

Three knife-wielding attackers in a van plowed into pedestrians on London Bridge on Saturday evening before going on a stabbing spree in nearby streets and bars in what authorities described as a new trend in militant Islamist terrorism. Police said they will release the names of the attackers as soon as operationally possible.

Seven people died and at least 48 others were injured, some of them critically, in the attacks on the bridge and in the nearby busy Borough Market area. Police shot dead the three men, who were wearing what looked like explosive vests that later turned out to be fakes.

The so-called “Islamic State” (IS) group claimed responsibility for the London attacks late on Sunday, the group’s affiliated Amaq news agency reported according to the SITE monitoring group. IS often makes such claims not only when it sends attackers, but also when others carry out plots inspired by the group’s extremist ideology.

International condemnation

World leaders were quick to condemn the attacks.

German Chancellor Angela Merkel said in a statement that her thoughts were with victims and their families and that Germany “stood firmly and resolutely at Great Britain’s side against every form of terrorism.”

US President Donald Trump offered US assistance to Britain but also used the incident as an opportunity to call for his ban on travelers to the US from several Muslim countries – which he sees as a security measure – to go into force.

French President Emmanuel Macron said on Twitter that “France is standing more than ever side by side with the UK.” France itself is still under a state of emergency after a string of Islamic extremist attacks.

Tonight, at 12:45 am, I will turn my lights off to pay tribute to the victims of the London attack.

London Mayor Sadiq Khan called on British citizens not to be cowed by the attacks and to vote on Thursday, as “one of the things these terrorists hate is voting; they hate democracy.” He also announced that a vigil for the victims will be held on Monday evening near Tower Bridge.

Bars and cafes targeted

There were still 36 people receiving hospital care on Sunday afternoon and 21 of them were in critical condition, according to officials. A London Transport Police officer armed only with a baton when he confronted the attackers was among those seriously injured with face, leg and head stab wounds.

Germany’s Foreign Ministry and Interior Minister Thomas de Maiziere confirmed on Sunday that two Germans were hurt in the attack, including one person who was severely injured. A Canadian and a Frenchman were killed in the attack while a Spanish citizen, one Australian and four French people were also among the wounded.

Australia’s Foreign Minister Julie Bishop said on Monday that three Australians were among those injured.

At the time of the attacks – around 10:00 p.m. local time (2100 UTC) – streets around London Bridge and Borough Market were crowded with people enjoying a Saturday night out in the district’s fashionable bars and restaurants.

Firing a total of 50 bullets, eight police officers managed to kill the attackers within eight minutes of receiving first emergency calls.

Election campaign pause

The attacks came days ahead of a June 8 national election, and less than two weeks after 22 people were killed in a suicide attack in the northern city of Manchester while attending a concert by US pop singer Ariana Grande.

Both the ruling Conservative Party and the Labour Party said on Sunday they would suspend their national campaigning for the upcoming election for a day.

Saturday’s attacks bore similarities to one in March on Westminster Bridge in London, in which a man plowed into a crowd of pedestrians, killing five, and then stabbed a police officer to death in the grounds of parliament before being shot dead.

May: ‘Too much tolerance of extremism’ 

Following a meeting of the government’s COBRA emergency committee on Sunday, British Prime Minister Theresa May made a statement in which she called for increased unity in face of the terrorist threat.

“We cannot and must not pretend that things can continue as they are,” May said, calling for more international control of the internet to take away terrorists’ “safe spaces” to spread their ideology and gain recruits. She added that in the real world “there is – to be frank – far too much tolerance of extremism in our country.”

May said Saturday’s attacks were not connected to the Manchester and Westminster attacks in planning, but they were inspired by a “single, evil ideology of Islamist extremism” that perverted Islam as irreconcilable with Western values of tolerance and democracy.

She concluded her comments by saying: “United we will take on and defeat our enemies.”
