LONDON (AP) -- The Latest on the attacks in the London Bridge area (all times local):
The SITE Intelligence Group says Islamic State's news agency is claiming fighters for the extremist group carried out the van and knife attack in London that left seven people dead.
SITE said in a statement Sunday that the Islamic State's Aamaq news service cited "a security source" in the Arabic-language posting claiming the attack.
Islamic State has often made such claims not just when it has sent attackers, but when extremists carrying out deadly plots were inspired by the group's ideology.
It's the third attack this year that Islamic State has claimed in Britain, after the bombing in Manchester and a similar attack in the heart of London in March.
The three attackers in Saturday's attack have not been identified.
London's police counterterrorism chief says the public should expect to see increased security measures as authorities investigate the latest attack to strike Britain.
Assistant Police Commissioner Mark Rowley said Sunday that police need to establish whether others were involved in planning Saturday night's vehicle and knife attack on London Bridge and at nearby restaurants.
Seven people were killed in the attack and 21 are in critical condition.
Rowley says 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 says 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.
London's assistant police commissioner says 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.
The attackers were shot dead. Rowley says they had "already killed members of the public and had to be stopped immediately."
Canadian Prime Minister Justin Trudeau says a Canadian is among those killed in the terrorist attack in London.
Trudeau said in a statement Sunday he is heartbroken.
Trudeau says Canada strongly condemns the senseless attack and stands united with the British people.
He says the Canadian government will not provide more details about the citizen killed in Saturday night's attack out of respect for the family.
British Prime Minister Theresa May has paid a private visit to some of the victims of the vehicle and knife attacks in central London.
May visited King's College Hospital, which is caring for 14 of the 48 people hospitalized after the Saturday night attacks on London Bridge and at nearby restaurants.
The National Health Service says 21 people remain in critical condition.
A van mowed down pedestrians on the bridge before its occupants got out and started stabbing people. Police shot three attackers dead.
Hundreds ran for their lives in the chaos.
Former Secretary of State John Kerry says Britons are going to have to sort out whether tolerance of extremism has gone on for too long, as British Prime Minister Theresa May has said.
Kerry tells NBC's "Meet the Press" that "a lot of ingredients" went into the attacks on London Bridge and at nearby restaurants Saturday night that left seven dead and nearly two dozen injured. Twelve people have been arrested.
He says one of the issues the country needs to get a handle on is the experience of Muslim residents, who've "had a long-standing problem with respect to greater levels of alienation, a harder time assimilating into the broader British society."
Kerry says the answer lies in building community to lessen the distance between governments and their people, a gap he thinks is a problem "all over the world."
Germany's Foreign Ministry says German citizens were among the people wounded in the attack in London, and one of them has serious injuries.
No further details were available Sunday on the Germans who were injured or the exact number.

A Romanian chef has been hailed as a hero on social media after he took in some 20 terrified people in the bakery where he worked as attackers targeted restaurants and bars in Borough Market.
Florin Morariu, who works at the Bread Ahead bakery in the market, told The Associated Press: "We were looking out of the window because we saw that everyone was agitated, everyone was running, people, women... they were fainting, falling and we went outside to see what was happening."
He said when he went outside and saw two people stabbing others, he at first "froze" and didn't know what to do. But then he went and hit one of the attackers on the head with a crate.
"There was a car with a loudspeaker saying `go, go' and they (police) threw a grenade.... and then I ran."
He added that when he saw that "people were desperate," he let about 20 people into the bakery and pulled the shutters down.
France's minister for Europe says that four French citizens are among the dozens of wounded in the London terror attack that killed seven people.
Marielle de Sarnez expressed her condolences to the families affected and "absolute solidarity" with the British in a statement on Sunday.

Philippe noted the attack came as French living overseas begin voting in advance of June 11 first-round legislative elections. He said voting in London would continue with reinforced security.
