Five Londoners have been released on bail following their arrest on suspicion of plotting to carry out a terror attack at RAF Fairford on Sunday morning.
The male suspects were arrested by police at the RAF base near Whelford in Gloucestershire, which is currently being used by the US.
They were detained on suspicion of offences under the Explosives Act and later, preparation of a terrorist act contrary to section 5 of the Terrorism Act.
All five were released on bail on Monday afternoon pending further enquiries.
Police were first alerted to the men after a local farmer reported a group of masked men and three suspicious vans near the RAF base at around 1.36am.
Dozens of homes were then evacuated and bomb disposal teams were dispatched to handle the incident and arrest the men. A 400m cordon was also put in place.
The farmer has since been praised by UK Defence Secretary Wes Streeting for alerting authorities to the alleged “terror plot”.
Counter-terrorism police have been investigating links between the plot and Iran, which has historically used proxies to carry out terror crimes in the UK.
But Iran has “categorically rejected” any suggestion that it is linked to the five arrests.
It was revealed on Monday that the five suspects are UK nationals - all from London.
But what else do we know about the suspects involved in the RAF Fairford “terror” plot?
Everything we know about the RAF Fairford ‘terror’ plot
What do we know about the five arrested men?
Police have released limited information about the five men arrested over the suspected bomb plot at RAF Fairford.
All men are all in their 20s and are all from London. They are a 24-year-old from Camden, north London; three men aged 23, 24 and 25 from Westminster, and one aged 24 from Willesden, north-west London.
The motive or exact plans of those arrested is currently unknown and it is also unclear if anybody else was involved in the suspected plot.
The Counter Terrorism Police have asked for “space” as they work to establish a motive for the incident.
The suspects are now expected to be released on bail following “extensive interviews.” This does not mean that the investigation is over and police will continue to explore multiple lines of enquiry.
Were authorities aware of a terror plot?
The question of what the police knew and when has been hotly discussed.
Some local villagers told the BBC that security around RAF Fairford had been ramped up in recent days prior to the arrests, suggesting that authorities may have had an idea that something was being planned.
One villager claimed to see a man wearing a backpack in bushes near the airbase, while another said they were told by armed police to return home and stay indoors.
However, Whitehall sources known to the BBC said the operation was not “intelligence-led.”
US President Donald Trump has claimed the contrary and insisted the suspects had been under surveillance for a long time.
Mr Trump alleged to reporters in the US that the men “were looking to do big damage” and that the US and Britain had worked together to arrest the men.
He said: “We had them under view for a long time, and we got them.”
Defence secretary Wes Streeting praised the farmer who dialled 999 to alert authorities to the five masked men and the three vans.
He told Sky News: “Thank you to that member of the public. She has done exactly what we would hope that someone in that extraordinary situation would do.
“I’m grateful to her - I think she acted, by her own admission, quickly and thoughtfully, and she did the right thing.”
However, the defence secretary added that the woman only had a “partial picture”. He went on to hint that UK security services were aware of the incident and did not refute comments made by the US president.
Roz Savage, MP for South Cotswolds has called for clarity on the events.
“There does seem to be two incompatible accounts of who knew what and when,” she said.
“The president is saying this was all coordinated, but it seems people here and on the ground and local police were not aware of a joint intelligence operation.”
What has Andy Burnham said about the incident at RAF Fairford?
Prime Minister Andy Burnham is set to chair a Cobra meeting this afternoon following the incident at RAF Fairford.
The Prime Minister has been at the Labour Party Conference, but will meet with officials to get “the full picture”.
He thanked the police, the security services, the emergency services, and the public for their action.
What has the police said?
In its latest update, police have confirmed that the five men were beingreleased on bail pending further enquiries.
Head of Counter Terrorism Policing Laurence Taylor said in a police update that the investigation is not over.
He urged the public “to remain vigilant” and to return to “normality” as quickly as possible.
Mr Taylor added that authorities would be examining the case from all angles to determine whether the alleged plot was organised by proxies.
What did the farmer say?
It is understood that a farmer alerted police to the suspected “terror plot” in the early hours of Sunday morning.
The local woman dialled 999 after she spotted a large group of hooded and masked men alongside three suspicious vans.
"When they saw me they ran ahead of me - some into the field and some towards the neighbouring village," she told the BBC. "I then realised that something highly unusual was taking place."
It is believed that the woman attempted to contact the Ministry of Defence, but did not receive any response. She then dialled 999, prompting an emergency response from local forces.
She added: “I believe that my 999 call foiled whatever plans they had.”
The woman also sent a message to a local neighbourhood Whatsapp group.
The message reads: “In case anyone is awake…something very odd is going on in the village.
“The road by the village hall is blocked by three white vans and we saw a group of masked men. I’ve called the police to report.”
