JERUSALEM (JWN and agencies)—A prominent Iranian nuclear scientist was killed by a bomb attached to his car Wednesday by the passenger on a passing motorcycle, according to the semi-official Fars news agency.

The murdered scientist, Mostafa Ahmadi Roshan, 32, was a department head at the Natanz uranium enrichment facility in Isfahan.

Witnesses said the motorcyclist slapped a magnetic bomb to the side of Roshan’s car and sped off just before it exploded, killing the scientist and wounding two of his passengers.

Fars quoted Deputy Governor Safarali Baratloo as blaming Israel for the bombing, which was similar to other attacks on Iran’s nuclear scientists.

“The bomb was a magnetic one and the same as the ones previously used for the assassination of the scientists, and is the work of the Zionists [Israelis]” Fars quoted Baratloo as saying.

Tehran has blamed the killings on both Israel and the US, both of which have denied the accusations.

Iran’s Atomic Energy Organization said the country’s nuclear course would not change after what it called the “heinous act.”

“We will continue our path without any doubt … Our path is irreversible,” the organization said in a statement quoted by Iran’s Arabic language Al-Alam TV.

“The more you kill us, the more our nation will become awakened as our late leader of the Islamic revolution Ayatollah Ruhollah Khomeini had said,” the statement concluded.

In a related development, the leading French daily Le Figaro quoted a security source in Baghdad Wednesday as saying that Israeli Mossad agents are recruiting and training Iranian dissidents in Iraq’s Kurdish region to work against the regime in Tehran.

There have been foreign media reports the past that the Mossad has been recruiting Iranians opposed to the ayatollah regime in Tehran and uses them to carry out bombings. Israel has denied the reports.
