A prominent Iranian University professor has been assassinated by unknown terrorists, informed sources with the Iranian police say.

Daryoush Rezaienejad and his wife were on their way to their child's kindergarten when they were approached by two men on motorbikes. The gunmen called him by name and shot Rezaeinejad, 35, in the neck when he turned around.

The gunmen chased Rezaeinejad's wife who attempted to find help for her husband. She is currently in hospital, a Press TV correspondent reported.

No group or individual has claimed responsibility for the attack.

Initially, local Iranian media had reported that Daryoush Rezaienejad was a nuclear physicist..

The confusion was apparently cause by the similarity between his name and that of nuclear physicist Daryoush Rezaei.

Local sources also say that Rezaeinejad was working for the Iranian Defense Ministry.

On November 29, 2010, two other Iranian academics became the target of terrorist attacks.

Unidentified terrorists detonated bombs in the vehicles of Dr. Majid Shahriari and Professor Fereydoun Abbasi in separate locations in Tehran. Shahriari was killed immediately but Abbasi and his wife sustained injuries.

On December 2, the Iranian Intelligence Ministry announced that Mossad, CIA and MI6 spy agencies played a role in those attacks.

Meanwhile, Resolution 1747 adopted by the United Nations Security Council in March 2007 against the Islamic Republic cited Abbasi's name as a "nuclear scientist," thus suggesting that perpetrators behind the assassination could be traced through those who included the professor's name in the UN resolution
