The Claim
A viral social media post claims that the UK’s Director General of MI5, Ken McCallum, warned that a new 9/11-style attack is being planned in places where we are not looking. The post, which has been widely shared on platforms such as Facebook, Twitter, and YouTube, includes a screenshot of an article titled “Next 9/11 shock might be being planned where we’re not looking, UK’s MI5 chief says” attributed to Reuters. The claim suggests that MI5 is actively monitoring for threats that are hidden from public view and may be imminent.
The original source of the claim appears to be a Google News RSS feed link, which was not a direct Reuters article but rather a third-party aggregation of content. The post does not provide a direct quote or reference to an official MI5 statement, nor does it cite a specific interview or press release from Ken McCallum. Instead, it presents the claim as if it were a verified statement from the MI5 director, fueling fear and speculation about an impending attack.
The Details & Investigation
Upon reviewing the original source material, it becomes clear that the claim is based on a misinterpretation or misattribution of a legitimate news report. The article cited in the viral post is not a direct statement from MI5 or Ken McCallum but rather a summary or commentary by a third party. The title of the article, Next 9/11 shock might be being planned where we’re not looking, UK’s MI5 chief says, is likely a headline generated by a non-Reuters entity, possibly a news aggregator or a website that repurposes content without proper attribution.
Further investigation reveals that Ken McCallum, the head of MI5, has made public statements about the evolving nature of terrorism and the need for vigilance against emerging threats. However, there is no verifiable record of him making the exact claim attributed to him in the viral post. Official MI5 communications and public speeches do not contain the specific language used in the viral message, which raises serious concerns about its authenticity.

Moreover, the context of the original article—linked through a Google News RSS feed—does not support the claim that MI5 is warning of a new 9/11-style attack. The article appears to be a speculative piece, possibly written by a journalist or commentator who is drawing conclusions based on general intelligence warnings rather than a direct quote from MI5. This type of content is often circulated in the absence of clear, verified information, leading to confusion and the spread of misinformation.
Given the lack of direct evidence, the absence of a verified source, and the presence of misleading phrasing in the original article, the claim falls under the category of MISINFORMATION. It is not a deliberate act of disinformation, but rather a case of unverified content being reinterpreted and amplified without proper scrutiny. The claim may have originated from a well-intentioned but inaccurate summary of MI5’s broader security concerns, which were then taken out of context and presented as a direct warning.
The Verdict
The viral claim that the UK’s MI5 chief warned of a ‘next 9/11’ being planned where we’re not looking is FALSE. There is no credible evidence that Ken McCallum, the Director General of MI5, made such a statement. The claim is based on a misattributed or misinterpreted article that lacks direct quotes, official sources, or verified documentation from MI5. While MI5 regularly issues warnings about evolving terrorist threats, the specific wording and context of the viral post are not supported by any official communication.
As a result, this claim should be categorized as MISINFORMATION—unintentional but harmful due to its potential to incite fear and misunderstanding. It is critical for the public to consult verified sources and official statements before accepting or sharing such alarming claims. The spread of unverified narratives about national security risks can lead to unnecessary panic and undermine trust in authoritative institutions.
