TEHRAN (FNA)- Head of the Islamic Revolution Guards Corps (IRGC) intelligence unit Hossein Ta'eb underlined that Iran is seriously pursuing the fate of its four diplomats who had been abducted by Phalange forces in Northern Lebanon in 1982.

"The relevant bodies are seriously pursuing the issue until attainment of final results," Ta'eb told FNA on Monday.

"We are not yet disappointed at obtaining results as we pursue the case," he added.

In relevant remarks yesterday, Son of former Iranian charge d'affaires in Beirut Seyed Mohsen Moussavi underlined that evidence and documents indicate that the four diplomats abducted in Lebanon are still alive and imprisoned in Israel.

"We could attain some information showing that Ahmad Motevasselian and his accompanying team are still alive," Moussavi's son said on Sunday.

"During the time, different reports have come from the Iranian diplomats and we conclude that they are alive and being kept in Israeli prisons," he added.

Moussavi's son stressed that legal works are underway in Lebanon to pursue fate of the four diplomats.

Also, in May, Iranian Defense Minister Brigadier General Hossein Dehqan said that Iran is in possession of corroborative evidence proving that its four diplomats are still alive and imprisoned by Israel.

"We claim on the basis of proofs that they are alive and captivated by the Zionist regime," General Dehqan said.

He underlined that the Israelis are responsible for the health of the Iranian diplomats, adding that Tehran will also pursue their fate legally and politically.

The then charge d'affaires of the Iranian Embassy in Beirut Seyed Mohsen Mousavi, military attaché Ahmad Motevaselian, embassy technician Taghi Rastegar Moghadam and journalist of the Islamic republic news agency Kazzem Akhavan were kidnapped by the Lebanese mercenary army - also known as the Falangists - at gunpoint in Northern Lebanon in 1982 and were later handed over to Israeli army.

Israel has released contradictory reports on the issue. The Zionist regime alleged in a statement last year that the diplomats had never been surrendered to Israel. Elsewhere it claimed in response to a request put forward by the Lebanese Hezbollah group that the four are already dead.

In January 2009, the then Iranian foreign ministry spokesman said that Iran had received a report from the Zionist regime which said the kidnapped Iranian diplomats had not been transferred to Tel Aviv and laid the blame on the Lebanese mercenary army affiliated with Israel.

In reaction to the report, the spokesman said at the time that the report "will not relieve the Zionist regime of its responsibility" for the healthiness and safe repatriation of the diplomats.
