8:25 a.m. ET: British police said they have arrested 12 people in east London over the London Bridge attack. Police said in a statement that counterterrorism officers made the arrests Sunday morning in Barking.

Police said the investigation is progressing rapidly.

A British Transport Police officer and an off-duty officer were among the injured in the Saturday night attack.

9:42 a.m. ET: The British Transport Police chief said that an officer who was wounded in the London Bridge attack was armed only with his baton when he confronted the three knife-wielding assailants. The officer, who was stabbed in the face, head and a leg, was one of the first responders.

British Transport Police Chief Constable Paul Crowther visited the officer at a hospital and said that he's in stable condition. Crowther said that "it became clear that he showed enormous courage in the face of danger." Crowther added that "for an officer who only joined us less than two years ago, the bravery he showed was outstanding and makes me extremely proud."

11:18 a.m. ET: British Prime Minister Theresa May has paid a private visit to some of the victims of the vehicle and knife attacks in central London.

The National Health Service says 21 people remain in critical condition.

Germany's Foreign Ministry said German citizens were among the people wounded in the attack, and one of them has serious injuries. France's minister for Europe says that four French citizens are among the wounded.

London's assistant police commissioner said eight police officers fired "an unprecedented number" of bullets at the three men suspected of carrying out the attack on London Bridge and at nearby restaurants. Assistant Police Commissioner Mark Rowley said during a news conference on Sunday that the officers fired 50 rounds at the men, striking and wounding a member of the public in the process.

Rowley says the injured civilian's injuries are not believed to be critical and there will be an independent investigation.

4:19 pm. ET: Social media giants Google and Twitter have responded to May's statement that internet companies are complicit in terror attacks by giving extremist views "the safe space it needs to breed."

Nick Pickles, UK head of public policy at Twitter, said: "We continue to expand the use of technology as part of a systematic approach to removing this type of content." Google said, "We are committed to working in partnership with the government and NGOs to tackle these challenging and complex problems, and share the government's commitment to ensuring terrorists do not have a voice online."

London police haven't said what role, if any, social media or information from the internet factored into Saturday night's attack.

London's police counterterrorism chief said the public should expect to see increased security measures as authorities investigate the attack. Assistant Police Commissioner Mark Rowley said that police need to establish whether others were involved.

He said police are confident that the three men fatally shot by officers in the minutes after the assault were the only attackers, but there is "clearly more to do" in the investigation. He said the white van they used to mow down pedestrians on London Bridge was rented by one of the men.

Security cordons will remain around London Bridge indefinitely.

4:23 pm. ET: France's foreign minister, Jean-Yves Le Drian, has announced that a French citizen was among those killed and that another remains missing. He said that seven other French nationals are hospitalized, four of them in serious condition.

Jibril Palomba, a resident of a suburban London town where police have conducted a raid, said he thinks one of the London Bridge attackers was a neighbor who was known for religious proselytizing. Palomba said he recognized the man who lived in an apartment armed police raided early Sunday in Barking as one of the dead assailants in a widely published photo.

Palomba said he and his wife first encountered the neighbor after his wife became concerned about how the man spoke to their children and others in a local park "about religion, Mohammed, this kind of stuff." He said that his wife reported the neighbor's behavior to police, but nothing came of it. He also said that he later became friendly with the man and never suspected he could be planning attacks.

4:37 p.m. ET: British national Brett Freeman was stabbed four times and has been recovering in a hospital. His friend took a picture and posted it on Twitter with the caption: "He's a soldier."

Two Australian citizens and a New Zealand citizen were also among the injured.

5:15 p.m. ET: Officials have released the identity of the Canadian victim who died as a result of the attack. Christine Archibald's family released a statement saying they grieve the loss of their daughter and sister.

"We grieve the loss of our beautiful, loving daughter and sister. She had room in her heart for everyone and believed strongly that every person was to be valued and respected. She lived this belief working in a shelter for the homeless until she moved to Europe to be with her fiancé," the statement read. "She would have had no understanding of the callous cruelty that caused her death. Please honor her by making your community a better place. Volunteer your time and labor or donate to a homeless shelter. Tell them Chrissy sent you."

8:06 a.m. ET: Speaking at the scene of the attack, the Mayor of London, Sadiq Khan, described the actions of the men who killed seven people and injured scores of others on Saturday night in London as "cowardly" and "evil," and he said they did not represent Islam. He said vigil has been scheduled for Monday evening near the site of the attack.

Khan also appeared to suggest that he does not welcome a state visit to the United Kingdom from U.S. President Donald Trump. While addressing police funding, Khan mentioned London's other responsibilities as a capital city. "From major events, there's a big cricket match today, to state visits - some welcome, some less so," he said. "But the fact is we need to make sure the police have the resources and support they need, and as the mayor my job is to make our city safe and I'll do my best as the mayor to be an advocate and champion for our police to get the tools they need."
