Iranian Men Charged Over Foiled Chlorine Bomb Plot Targeting Manchester Synagogue

Key points

• Rahman Salehi, 34, and Salam Ahmadyan, 36, appeared in Westminster Magistrates' Court charged with preparing acts of terrorism on or before September 20, 2026.
• Prosecutors allege the men acquired materials and instructions to build a chlorine bomb and conducted 'hostile reconnaissance' on sites including the Jewish Museum and Heaton Park Synagogue.
• The suspects were arrested in Manchester's Northern Quarter on the eve of Yom Kippur, the holiest day in the Jewish calendar, and were remanded in custody until October 23.
• Metropolitan Police state the men were in contact with a third party, likely an Iranian national operating from within Iran, who directed the plot.
• The charges come one year after the October 2025 attack on Heaton Park Synagogue, which killed two people, and amidst broader concerns over Iranian-linked threats in the UK.

Background

This development follows the one-year anniversary of the October 2, 2025, attack on Heaton Park Hebrew Synagogue in Manchester, where Jihad Al-Shamie killed two worshippers during Yom Kippur services. The current charges also occur alongside a separate security incident at RAF Fairford, where five British nationals were arrested in late September on suspicion of terrorism. While Prime Minister Andy Burnham suggested Iran played a part in the airbase incident, counterterrorism officials explicitly stated the Manchester plot and the RAF Fairford case are not connected. The suspects in the Manchester case arrived in the UK via small boats in 2020 and 2023, respectively, with Salehi having previously claimed asylum in Germany.

How outlets are covering it

All four sources confirm the core facts of the charges, the suspects' identities, and the alleged chlorine bomb plot. However, they differ in emphasis regarding the broader security context. The BBC and The Guardian focus heavily on the specific details of the Manchester plot, the suspects' immigration status, and the emotional impact on the local Jewish community, noting the timing relative to Yom Kippur and the anniversary of the previous attack. CBS News and NBC News place greater weight on the simultaneous RAF Fairford incident, highlighting the UK government's accusations that Iran is involved in multiple threats, while noting Tehran's denial. NBC News explicitly quotes counterterrorism officials clarifying that the Manchester and RAF Fairford cases are distinct, whereas CBS News frames the Manchester charges as part of a 'spate of attacks' targeting Jewish or Israel-linked locations in the capital.

Why it matters

The case underscores persistent security concerns regarding Iranian-linked terrorism in the UK, particularly targeting Jewish communities. The timing, coinciding with Yom Kippur and the anniversary of a fatal synagogue attack, highlights the ongoing vulnerability of these communities. Additionally, the case intersects with political debates over immigration, as Home Secretary Shabana Mahmood cited the suspects' arrival by small boat as a reason to strengthen border security, while counterterrorism officials reassured the public that the specific plot does not pose an ongoing threat.

What to watch

The two suspects are remanded in custody and are scheduled to appear at the Old Bailey in London on October 23, 2026. Investigations into the third party in Iran and the broader network of threats, including the separate RAF Fairford incident, are expected to continue as UK authorities maintain heightened security measures.
