British Prime Minister Theresa May called for Internet giants to crack down on terror in the wake of Friday’s London bombing.

May said she’d bring up the topic with other world leaders at the UN General Assembly in New York next week.

“One of the issues that we really need to be addressing — and I’ll be raising this when I’m at the United Nations — is the question of the use of the Internet by terrorists,” May told ABC News in an interview that will air Sunday on “This Week.”

“But also this using it for the spread of extremism, of hatred, of propaganda that can incite and can inspire terrorism.”

British security services raised the terror threat level from “severe” to “critical” following the attack in the London subway.

“The police and the security services are doing the work necessary to discover the full circumstances of this cowardly attack that’s taken place, and to identify all those who are responsible,” May told ABC.
