UK police ‌say they have re-arrested ‌two men on suspicion of assisting a foreign intelligence service ‌as ‌part ⁠of their investigation into ​activity at the RAF Fairford air base last month.

Counter ⁠Terrorism ‌Policing said ​in a ​statement that ‌they had re-arrested a ​24-year-old UK citizen who ​was initially arrested outside the military base in south-west England in the early hours of September 27.

Police said they had also arrested ⁠a 25-year-old UK-Iranian ​dual ​citizen who had previously been arrested in London.

Assistant Commissioner ​Laurence Taylor, ‌head of National Counter Terrorism Policing in the UK, said in a ​statement: “This is very much a live investigation, and our evidence gathering continues but at this time our position remains the same; ​we consider ​it highly likely that ​there is Iranian state involvement.”

UK ​Prime Minister Andy Burnham ‌last week said that the activity at RAF Fairford, which had been used by US bombers to carry out strikes on ​Iran, was likely to have ​been co-ordinated in ⁠Iran.

“We know the public have unanswered questions,” CTP’s Taylor said.

“I ​want to be as transparent as possible and when we ​are in the position ⁠to share more, we will.”
