British police released on bail five London-based men in their 20s arrested near RAF Fairford, an airbase used by US bombers during the Iran war, amid an investigation into whether a 'foreign state' was involved in a suspected bomb plot. Iran's embassy in the UK 'categorically' denied any involvement, calling the allegations 'unfounded and malicious' and threatening legal action, while UK officials, including Defence Minister Wes Streeting, said it was 'too soon' to blame a foreign state. US President Trump said he was 'surprised' the suspects were freed and suggested the case 'might be' linked to Iran without providing details, while UK Foreign Secretary Miliband vowed Britain would act against Iranian 'proxies' and would not tolerate hostile activity on British soil. The incident has heightened scrutiny of alleged Iranian-linked threats within the UK.
