Good morning and welcome to our coverage of events at RAF Fairford in Gloucestershire as counter-terrorism police investigate whether Iran is behind a suspected bomb plot at the base which is used by the US military to carry out missions in the Middle East.
Five men detained near the base early on Sunday were initially detained over explosives offences and then were further arrested later in the day on suspicion of the preparation of a terrorist act. Pictures of the men with their shirts off could point to a precautionary measure against the risk of suicide vests or concealed weapons.
It came after armed officers found explosives on three vans parked minutes from the base. The suspected plot appears to have been foiled by chance when a member of the public spotted unusual behaviour late at night in the countryside from a group of men and called 999.
Dozens of households in the Cotswolds village of Whelford were evacuated during the operation and have still not returned to their home.
