UK Counter Terrorism Policing investigates radiological-drone threat video against Israeli embassy after Iran-linked group Harakat Ashab al-Yamin al-Islamia claim

Metropolitan Police, CBRN specialists, and fire-investigation units flooded Kensington Gardens in full hazmat suits on Friday after an Iran-linked Islamic group calling itself Harakat Ashab al-Yamin al-Islamia posted video showing operatives in protective suits preparing drones marked with its logo, threatening delivery of radioactive and carcinogenic material onto the nearby Israeli Embassy. Counter Terrorism Policing opened an inquiry into the video's authenticity and into discarded items recovered at the scene. Both the Met and the Israeli embassy said no attack occurred. The incident escalated a London-area arson and intimidation pattern targeting Israeli- and Jewish-linked sites since the 2026 Iran war ceasefire.

Analysis
The claim is very likely a hoax or influence operation, but the Met's CBRN callout and recovery of discarded items on-site raise the sharper question of how Harakat Ashab al-Yamin al-Islamia achieved UK operating presence sufficient to stage the footage. Jewish Chronicle, LBC, and Times of Israel corroborate, with Soufan Center framing placing it in the post-Iran-war European threat trajectory. UK Counter Terrorism Policing will likely attribute the group's command structure to Iran-aligned proxy networks within the coming weeks, consistent with MI5's public warnings of 20-plus disrupted Iran-directed plots in the past year and the incident's tight temporal clustering with the Lebanon ceasefire and Hormuz restrictions; the concurrent London arson campaign against Jewish-linked sites strengthens the read that Iran is running a low-cost, high-visibility intimidation line rather than pursuing mass-casualty tradecraft. The group may instead be an unaffiliated ideological copycat exploiting the Iran-war atmosphere, which would push UK response toward domestic radicalisation channels rather than state-threat architecture.
