LONDON: Arms dealers linked to Yemen’s Houthi militia have been using social media platforms such as X and WhatsApp to sell weapons, according to a new report.
The Tech Transparency Project, or TTP, identified hundreds of accounts openly dealing in rifles, rocket-propelled grenades and other military-grade equipment, in apparent violation of the platforms’ policies.
“X and WhatsApp are providing an essential platform to Houthi-linked arms dealers selling weapons of war,” the report read. “The companies have policies in place that prohibit that kind of illicit trade but are allowing it to take place in the open.”
TTP called the activity “a threat to US national security interests,” noting the Iran-backed group is designated as a terrorist organization.
The months-long investigation by the Washington-based watchdog, which monitors accountability in Big Tech, found that Houthi-affiliated arms dealers had been running commercial weapons stores on both platforms for months, and in some cases, years.
Researchers identified at least 130 Yemen-based X accounts and 67 WhatsApp business accounts advertising military-grade equipment or promoting catalogues of guns for sale. These included US-manufactured weapons — some marked “Property of US Govt” — and other Western arms labeled with “NATO.”
In one instance, a seller listed four M4 carbines — an assault rifle used by the US military and manufactured by FN Herstal and Colt — and directed buyers to WhatsApp. Another account offered a package deal that included a ballistic helmet, night-vision goggles and grenades.
Russian weapons, including RPG-7 launchers and AK-47s, also featured prominently. A Soviet RPG-7 was offered for about $1,800, while another account advertised a “zero mileage” Russian AK-47.
Prices for some weapons reportedly reached $10,000, suggesting sales may be intended for other armed groups or insurgents.
Many of the accounts displayed allegiance to the Houthi, including photos of weapons in crates marked with Houthi slogans such as “Death to America, death to Israel.”
More than half of the X accounts listed Sanaa — under Houthi control for more than a decade — as their location. Many accounts funneled buyers to WhatsApp business profiles, some of which openly displayed catalogs of rifles and ammunition. A number of these were also linked to Facebook and Instagram accounts, raising further concerns over Meta’s enforcement of its firearms policies.
Meta, which owns WhatsApp, says it reviews all images submitted to product catalogs, yet researchers found little evidence of enforcement. The company said it had since removed several accounts and claimed it does not profit from this type of activity but declined to answer how the content had bypassed existing filters.
“X and WhatsApp both have policies against weapons sales but they are allowing arms traders linked to a US-designated terrorist group to traffic weapons on their platforms,” said Katie Paul, the director of TTP.
“In some cases these companies may be profiting off violations of their own policies that create risks for US national security.”
TTP’s findings, which build on a similar August 2024 investigation by The Times, suggest most of the Houthi-linked arms dealer accounts were created or became active following mass layoffs at X and Meta that weakened enforcement capabilities. Many handles had blue ticks and were subscribed to premium services that are supposed to be moderated.
Roughly two-thirds of the accounts appear to have posted weapons content in the past six months.
“Both Meta and X have the capital, the tools and the human resources to address this problem, but they’re not doing so,” Paul said.
