Five young British men arrested on explosives and terror charges near a U.S.-operated air force base in England were released on bail Monday, and counterterror detectives said they were investigating “multiple lines of inquiry,” including whether there is a link to Iran.
The men were detained early Sunday after three vans were spotted in the countryside near RAF Fairford, a U.K.-owned base that has been used by American bombers during decades of conflicts in the Middle East, including this year’s war with Iran.
Investigators haven’t concluded whether the incident was state-backed. They are investigating a possible link to Iran, Russia or non-state militant groups. RAF Fairford has also been the focus of protests by anti-war campaigners.
The five suspects, who haven’t been named, were initially held over suspected explosives offenses, and later also arrested on suspicion of preparing an act of terrorism. Police said the men are all British nationals from London and in their 20s.
Britain’s national news agency, PA, reported without citing sources that police had not found viable explosives. Announcing that the suspects had been bailed, the head of U.K. Counter Terrorism Policing, Laurence Taylor, said that the suspects face stringent conditions and “absolutely remain under investigation.”
Taylor said lines of inquiry include that the suspected offenses were committed by “proxies or individuals, either knowingly or unknowingly, working on behalf of a foreign state.”
Iran denied involvement. The Iranian Embassy in London said that it “categorically rejects and strongly condemns the recent unfounded and malicious speculations” about the incident.
Residents were evacuated from 85 homes in the village of Whelford near the base on Sunday, and army bomb-disposal experts used a robot to examine three white vans.
Home Secretary Shabana Mahmood said Monday afternoon that “thanks to the excellent work of the army’s explosive ordnance disposal team,” the scene was now safe and residents could go home.
Prime Minister Andy Burnham said he would chair a meeting of the government’s COBRA emergency committee later Monday “to make sure we have the full picture.”
