Five people arrested in a "major incident" at a British air force base are all British nationals.

British counter-terrorism police said on the 28th that the five men arrested in the incident at Royal Air Force Fairford in the UK are all British nationals, all in their 20s, and all from London. All five are currently being held under the Police and Criminal Evidence Act. British counter-terrorism police said investigators are still looking into the specific circumstances of the arrested individuals' activities, the information they possessed, and the motive behind the incident, describing it as "an extremely complex and large-scale operation." On September 27 local time, British police said a "major incident" occurred at a US military-used air base in the UK, several men were arrested, and multiple residences were evacuated.
