A war of words between the United Kingdom and Iran is intensifying after British Prime Minister Andy Burnham said a suspected security plot involving RAF Fairford was highly likely to have been coordinated in Iran and almost certainly directed by the Islamic Revolutionary Guard Corps (IRGC). Tehran has denied involvement and called on Britain to provide evidence. Seven men have been arrested in connection with the investigation, but all have been released on bail and no charges have been filed. The incident has heightened security concerns around the air base, which has hosted US bombers used in strikes against Iran. Britain has also announced further sanctions targeting Iranian-linked individuals. Could the dispute trigger a wider escalation? There is no confirmed report that London is an Iranian missile target.
