Iran has arrested a Lebanese-American citizen on suspicion of having links to US intelligence services. He has become fifth American citizen held by Iran, state television announced on Tuesday.
Although the television report did not give any information regarding when or where the suspected individual had been arrested, the report identified him as Nezar Zaka and said he is suspected of multiple close ties to the US military and intelligence agencies.
Four Iranian-American citizens also have been arrested in Iran including Washington Post correspondent Jason Rezaian, who has been taken in since July last year for spy charges.
Iranian Foreign Minister Mohammad Javad Zarif said Iran is trying to resolve Rezaian's case "from a humanitarian point of view".
Iranian authorities also arrested American-Iranian businessman Siamak Namazi in mid-October while he was visiting family in Iran, according to a source speaking to the Associated Press.
The Iran administration does not recognise dual nationality for its citizens and treats them as all as Iranian citizens.
