US denies killing Iran nuclear scientist with magnetic bomb
'Western powers and their allies appear to be relying on covert war tactics to try to delay and degrade Iran's nuclear advancement,' security expert says
1:15 p.m. ET: The Obama administration is denying any role in the killing of an Iranian university professor working at a key nuclear facility. White House spokesman Tommy Vietor said the U.S. "had absolutely nothing to do" with Mostafa Ahmadi Roshan's death and the U.S. condemns "all acts of violence, including acts of violence like what is being reported today."
Published at 9:46 am ET: Two assailants on a motorcycle attached a magnetic bomb to the car of an Iranian university professor working at a key nuclear facility, killing him and wounding two people on Wednesday, a semiofficial news agency reported.
The attack in Tehran bore a strong resemblance to earlier killings of scientists working on the Iranian nuclear program.
It is certain to reinforce authorities' claims of widening clandestine operations by Western powers and allies to try to cripple nuclear advancements.
The bomb killed Mostafa Ahmadi Roshan, a chemistry expert and a director of the Natanz uranium enrichment facility in central Iran, the semiofficial Fars news agency reported.
Natanz is Iran's main enrichment site, but officials claimed earlier this week that they are expanding some operations to an underground site south of Tehran with more advanced equipment.
