British Prime Minister David Cameron's office says his country will review its scrutiny of far-right extremist groups after Friday's mass killings in Norway.

The prime minister chaired a meeting Monday of the National Security Council to determine whether Britain's security agencies have given what the council calls adequate scrutiny to the right-wing groups. It also looked at the implications for Britain from the Norway bombing and shooting attack that killed 76 people.

Anders Behring Breivik, the chief suspect in the Norway attacks, has claimed he was recruited by British right-wing extremists. Police are investigating any potential links.
