What this story says
- A group in northern Yemen used Anthropic's Claude AI to develop software for weapons, including a guided rocket and a ballistic missile with a range goal over 2,000 kilometers.
- Anthropic identified three weapons development programs: a guided rocket, a ballistic missile, and a hypersonic glide vehicle variant.
- The guided rocket was test-fired and failed, and the group returned to Claude to troubleshoot the issue, Anthropic reported.
- Anthropic banned the relevant accounts as soon as the illegal activity was detected and stated there is no evidence the actors succeeded in fielding an operational device.

Thin on the left so far
None of the 6 outlets with a published leaning rating that ran this story are rated left.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
An AI company, Anthropic, reported on September 10, 2026, that a group in northern Yemen used its Claude chatbot to develop guidance, navigation, and control software for weapons. The programs included a guided rocket, a ballistic missile with a range goal exceeding 2,000 kilometers, and a hypersonic glide vehicle variant. Anthropic stated that while they do not have evidence the actors succeeded in fielding an operational device, a guided rocket was test-fired and failed. The group reportedly returned to Claude to work out why the test failed.
Anthropic stated it banned the relevant accounts as soon as the illegal activity was detected. The company did not identify the actors, but reports suggest it is likely to involve the Iran-backed Houthi rebels, who control much of northern Yemen. The revelation comes as Houthi militants have been on the offensive in the country.
Disagreement on test-fire details
Anthropic stated that a guided rocket was test-fired and failed, and that the actors returned to Claude to work out why it failed. The Hindu reported that this field test appeared to have failed. Sud Ouest reported that the actors had conducted a test launch of a guided rocket that failed. Latestly reported that the test appeared to fail. The Siasat Daily reported that the test appeared to fail. Haberler reported that the group assigned engineering tasks to artificial intelligence while working on a missile targeting a range of over 2,000 kilometers. RayHaber and dunya.com also reported that the group assigned engineering tasks to artificial intelligence while working on a missile targeting a range of over 2,000 kilometers.

0 rated outlets
- The left-rated reports led on Anthropic's identification of a group in northern Yemen using its AI for weapons development. The Hindu, The Siasat Daily, and Al Jazeera all reported that a group in Yemen used Claude AI to build guided rockets and missiles. The Hindu and Al Jazeera mentioned the specific weapons programs, including a guided rocket, a ballistic missile with a range goal above 2,000 kilometers, and a hypersonic glide vehicle variant. The Hindu and The Siasat Daily noted that the guided rocket test-fire failed and the group returned to Claude to troubleshoot. Al Jazeera also mentioned global espionage in its headline.

- The centre-rated reports highlighted Anthropic's discovery of a Yemen-based group using its AI for missile development. Bloomberg and Sud Ouest reported that a group in northern Yemen used Anthropic's Claude AI model to support the development of missile and rocket systems. Both reports mentioned the specific weapons programs, including a guided rocket and a ballistic missile with a range goal of over 2,000 km. Sud Ouest also noted that the guided rocket test appeared to fail and that the group returned to Claude to troubleshoot. Bloomberg noted growing concerns over the use of advanced AI by non-state actors.

4 rated outlets
- The right-rated reports focused on the Houthis' alleged use of Anthropic's AI for weapons development. Latestly, n-tv, Le Figaro, brusselssignal.eu, NDTV, CNBC-TV18, Gulf News, and India Today all reported on the Yemen group's use of Claude AI for missile and rocket software. Several reports, including CNBC-TV18, Gulf News, and India Today, specified the types of weapons, such as a guided rocket, a 2,000km ballistic missile, and a hypersonic glide vehicle variant. NDTV and CNBC-TV18 mentioned the failed test-fire and the group's subsequent troubleshooting. Latestly and brusselssignal.eu also mentioned related cyber-espionage operations. India Today's headline questioned whether a failed missile test alerted Anthropic to the Houthis' use of Claude.
Questions about this coverage
- How did the left and right cover Yemen group used AI for guided weapons, Anthropic reports?
- Of the 6 outlets on this story carrying a published leaning rating, 0% are rated left, 33% are rated centre, 67% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 14. The sections above set out what each side emphasised, in its own terms.
- Is Yemen group used AI for guided weapons, Anthropic reports left or right?
- Too few of the outlets on this story carry a published leaning rating to say. 6 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
- Is the coverage of Yemen group used AI for guided weapons, Anthropic reports biased?
- Yemen group used AI for guided weapons, Anthropic reports is one event reported by 14 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Yemen group used AI for guided weapons, Anthropic reports?
- When we first saw this story, outlets rated left had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered Yemen group used AI for guided weapons, Anthropic reports?
- 14 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- What did the group in Yemen use Anthropic's AI for?
- A group in northern Yemen used Anthropic's Claude AI to develop guidance, navigation, and control software for weapons. This included a guided rocket, a ballistic missile with a range goal over 2,000 kilometers, and a hypersonic glide vehicle variant.
- Did the weapons developed by the group become operational?
- Anthropic stated they do not have evidence that the actors succeeded in fielding an operational device. However, a guided rocket was test-fired and reportedly failed, prompting the group to return to Claude for troubleshooting.
- What action did Anthropic take?
- Anthropic banned the relevant accounts as soon as the illegal activity was detected. The company also reported its findings to public and private partners to reduce risks.
