A Kuwaiti newspaper reported on Wednesday that Israel will soon receive new details regarding missing Israel Air Force navigator Ron Arad as part of a deal between Iran and a Western intelligence agency.

The Kuwaiti newspaper Al-Siasa quoted Western intelligence officials as saying that the deal includes the release of information regarding Arad, who's been missing in action since 1986, in exchange for details on four Iranian diplomats who vanished in Lebanon in the 1980s.

The report, which is based on Western intelligence sources, has not been confirmed.

The newspaper said that the deal has been enabled in light of recent improvement in ties between Iran and the West. According to the report, Hossein Mousavi, the brother of one of the Iranian diplomats that served in Lebanon and disappeared in 1982, was the one who transferred the information on the fate of Arad to the Western agency.

Arad's plane was shot down over Lebanon in 1986 and since then he has been missing in action. During that time, Mousavi served as an adviser to the Iranian foreign minister on the Middle East and the Arab world.
