Britain has asked Cyprus to extradite a dual British-Azerbaijani national suspected of spying on a British air base on the Mediterranean island and passing his findings to Iran’s Revolutionary Guards, London police ⁠said on Friday.

Rashad Sultanov, 44, ⁠from Islington in north London, is being held in custody by Cypriot authorities as extradition proceedings progress, the Metropolitan Police said in a statement.

The case marks Britain’s first overseas ​National Security Act investigation, led by ⁠counter-terrorism police into incidents at Britain’s RAF Akrotiri base in Cyprus between May 11 and June 22 last year, the statement said.

Police in ⁠Cyprus, where Britain has two ‌military bases, ⁠said the suspect was first arrested in 2025 and had been in custody since then. An Israeli minister at the time said Cypriot authorities had thwarted an attack ​on Israeli citizens.
