The head of the UK’s MI5 says the country faces a worsening mix of security challenges 25 years after the 9/11 attacks. Speaking as the anniversary is marked, Sir Ken McCallum says the UK is no longer dealing with the same threat landscape as in 2001 and warns that existing counter-terror and security measures must evolve.

Both outlets report McCallum’s message that defenders should not rely on past achievements, arguing that protections built “yesterday” must be complemented by capabilities needed for the future. He frames the current situation as one of “worst of both worlds,” suggesting both continued or new forms of threat are pressing at the same time.

The articles focus primarily on the speech and its broad warning rather than on specific incidents or policy changes. Metro emphasizes that the threats differ from those confronted in 2001, while the Evening Standard highlights McCallum’s call to resist complacency and keep updating defenses.
