Seven people died and up to 48 were injured when a terrorist attack unfolded in the heart of the British capital on Saturday night (June 3).
Officials said a vehicle barreled into pedestrians on London Bridge, and then three attackers embarked on a stabbing rampage at nearby Borough Market.
British Prime Minister Theresa May reacted to the attack Sunday morning in a short statement outside her official residence.
“We cannot and must not pretend that things can continue as they are,” she told reporters.
“There is far too much tolerance of extremism in our country.”
The incident was reported at 10:08 p.m. (5:08 p.m. ET) on Saturday. Within eight minutes, all of the suspects had been fatally shot by officers, according to authorities.
Metropolitan Police Assistant Commissioner Mark Rowley said the three men were wearing what appeared to be explosive vests but they turned out to be fake.
He added that all of the attackers were believed to have been killed but added that it was early in the investigation.
One of the those stabbed was a British Transport Police officer, who suffered serious but non-life threatening wounds. Forty-eight people were taken to hospitals in London, the ambulance service said.
Confirming the death toll had risen to seven on Sunday (June 4) Metropolitan Police Commissioner Cressida Dick praised the “extraordinary courage” of brave passers-by who stepped in to help those injured following the atrocity.
No terror group has claimed the attack, which comes after SIS issued a chilling instruction to its followers to launch an “all-out war” on the West to mark the start of Ramadan on May 26.
Witness Erick Siguenza told BBC News that one of the gang screamed “This is for Allah” as he went on his stabbing rampage.
It comes less than three months after an attacker ran down people with a vehicle on Westminster Bridge, killing four, then stabbed a policeman to death outside Parliament.
On May 22, a suicide bomber killed 22 people and injured dozens at an Ariana Grande concert in Manchester. After that attack, Britain’s official threat level from terrorism was raised to “critical,” meaning an attack may be imminent. Several days later it was lowered to “severe,” meaning an attack is highly likely.
