British police identify London attackers, make more arrests

The Met Police said the names of the attackers will be released "as soon as operationally possible", the BBC reported, adding that the police is still trying to figure out whether the attackers were part of a wider network.

Meanwhile, police carried out fresh raids on Monday and made some arrests in the ongoing investigation into the attack.

"A number of people have been detained," police said in a statement after two early morning raids in east London.

"A very high priority for us is to try to understand whether they were working with anybody else," London police chief Cressida Dick told BBC.

Dick said police had seized "a huge amount of forensic material" after going through the van used in the attack "very, very carefully".

"We will change and adapt to what appears to be a new reality for us," she said.

Saturday night's rampage at a popular nightlife hub around London Bridge by men wearing fake suicide vests was the third deadly terror attack in Britain in less than three months, and came only days before a general election.

British Prime Minister Theresa May on Sunday blamed "evil" Islamist ideology and vowed to crackdown on extremist content online worldwide, warning that attackers were "copying one another".

Meanwhile, the Islamic State group claimed responsibility for the attack via its propaganda outlet.

"A detachment of fighters from Islamic State carried out London attacks," the Amaq news agency said following the attack.
