Israel has detained an Iranian-Belgian citizen, accusing him of spying for Tehran.
Ali Mansouri has appeared before a judge but no formal charges have been brought.
The country’s Shin Bet intelligence service says he was arrested at Tel Aviv’s Ben Gurion airport on September 11.
It has released photos it claims Mansouri had in his possession, including a picture of the US embassy’s rooftop, taken from a nearby balcony.
According to the intelligence service, he was recruited as a spy by Iran and tried to develop business ties in Israel as a cover for espionage.
Belgium has confirmed that Mansouri married a Belgian citizen in 2002, acquired Belgian nationality and changed his name before getting divorced five years later and remarrying an Iranian.
The Belgian Foreign Minister Didier Reynders says nothing at this stage suggests anything illegal about the process.
The news coincides with the visit of the Israeli Prime Minister Benjamin Netanyahu to the UN where he is expected to argue that Iran still poses a serious threat to the West.
