Mostafa Ahmadi Roshan

The deputy head of Iran’s Natanz Nuclear Facility has been killed in a bombing in Tehran.

Mostafa Ahmadi Roshan was killed when a bomb exploded in front of Tehran’s Allameh Tabatabai University. A passenger in his car was later pronounced dead in hospital.

The Fars News Agency reports that at 8:30 AM, a motorcyclist snapped a magnetic bomb onto the victim’s car.

The Mehr News Agency cited eyewitnesses saying that a handmade bomb was attached to Ahmadi Roshan’s car and exploded after the car had continued another 200 to 300 metres.

The explosion reportedly shattered the windows of a neighbouring building.

An official was quoted as saying it was the type of bomb used in earlier attempts to assassinate Iranian scientists.

In 2009, Massoud Ali Mohammadi, a physics professor at Tehran University, was killed in a bomb explosion in Tehran.

In 2010, there were two bombings on the same day; one claimed the life of Iranian nuclear scientist Majid Shahriyari, but the other target, Fereydoon Abbasi, survived the attack and is now the head of Iran’s atomic program.

Iranian authorities blamed the earlier bombings on U.S. and Israeli conspirators.
