Tehran:
Iran's semi-official Fars news agency has denied that a physicist involved in the country's disputed nuclear program was assassinated.
The news agency said the wrong man was reported killed Saturday, leading to a mix-up.
The Fars news agency says the victim of Saturday's attack was Darioush Rezaeinejad, a university student in Tehran. Other news reports - including by the semi-official ISNA news agency - had identified him as Iranian physicist Darioush Rezaei.
Iran officials could not be reached for comment.
