UPDATED: British police have confirmed seven victims died and 30 people were injured in a terrorist attack that began on London Bridge and spilled onto nearby streets on Saturday night.

The three assailants were shot and killed by law enforcement after plowing a van into pedestrians on the bridge and then jumping out of the vehicle, wielding large knives and stabbing customers at a restaurant near busy Borough Market.

One of the victims stabbed was an on-duty police officer, who received serious but not life-threatening injuries.

According to Scotland Yard, the attackers were quickly shot and killed at Borough Market, a popular food destination located just underneath the south side of London Bridge. Police shot the three individuals within eight minutes of receiving the first call at 10:08 p.m. BST.

All three men were wearing what looked like explosives on their vests, but those turned out to be fake.

One woman was stabbed in the neck at a restaurant near Borough Market while a man was stabbed in the back at the same establishment.

The rampage sent scores of bystanders fleeing for safety and shut down at least two busy subway stations. London Hospital was also on lockdown to protect the victims, according to law enforcement officials.

Prime Minister Theresa May condemned the attacks as Britain suffered its third atrocity in 10 weeks. On Sunday morning, May convened an emergency meeting of Cabinet members to discuss the government’s response.

President Donald Trump offered America’s support to the U.K. on Twitter in a series of tweets.

The attacks come less than two weeks after the deadly suicide bombing at the Ariana Grande concert at the Manchester Arena. In the immediate aftermath of the bombing, the British government raised the nation’s terrorism threat level to “critical,” meaning that further attacks could be imminent. But a few days later, officials lowered it back down a notch to “severe.”

Grande sent prayers to the victims and their loved ones.

Grande’s benefit concert venue is on high alert, but the show is still scheduled to take place Sunday evening. She posted a photo to Instagram on Saturday of her hospital visit with one of the Manchester bombing victims.
