Questions remain over Iran’s link to alleged RAF Fairford bomb plot

Investigators may be some way from determining exactly what led five men with three vans to a village just outside RAF Fairford in the small hours of Sunday – but the fact they have all been released on bail without immediate charge suggests they are not deemed to pose a serious and violent threat.

In a moment where wider geopolitical tensions mean external threats are perceived to be close, the question of whether Iran had a hand in the alleged plot remains open. Nonetheless, the bailing of the men is a mercifully lower-key development in an investigation that appeared of the utmost gravity.
