Iran hanged on Tuesday a man found guilty of giving information on Iranian missiles to Israeli intelligence service Mossad, state news agency IRNA reported, quoting the Tehran prosecutor's office.
Ali Akbar Siadat was hanged in Tehran's Evin prison after having been condemned to death for "working for Mossad," said the prosecutor's office, IRNA reported.
Mr Siadat was found guilty of having had links with Mossad for six years, said IRNA.
"He had received 60,000 dollars to give classified information to the Zionist regime," IRNA reported.
IRNA said Mr Siadat had acknowledged having established contacts with one Israeli embassy overseas and that he had been giving information "about missiles belonging to the revolutionary guards."
He was also transferring information of Iranian military bases to the "enemy," IRNA said. Three years ago Mr Siadat had received a computer and other equipment for his work, the report added.
Mr Siadat used to meet his contacts from the Israeli intelligence service in Turkey, Thailand and Netherlands in different hotels, IRNA said.
He was arrested two years ago with his wife while trying to leave Iran, the report added.
Iranian media on Sunday announced that another Iranian had also been sentenced to death for working as a "spy" for Israel.
"This spy has been sentenced to death. His identity will be revealed after confirmation of the sentence," Tehran prosecutor Abbas Jafari Dolatabadi was quoted by Mehr news agency as saying on Sunday.
In late October, media reports quoted Dolatabadi as saying that two Iranians had been charged with spying for Israel, which accuses Tehran of seeking to develop atomic weapons under the guise of a civilian nuclear programme.
Iran routinely accuses arch-foe Israel of carrying out hostile activities against the Islamic republic, including espionage against its armed forces and against its nuclear programmes.
Iranian officials have accused the Israeli intelligence services, as well as the US and Britain, of attacking two of its top nuclear scientists on November 26.
Majid Shahriari, a senior scientist involved in Iran's nuclear activities, was killed by a bomb placed against his car. Fereydoun Abbassi Davani, another top nuclear expert, was wounded in a similar attack.
