TEHRAN, Iran — Iran's president accused Israel and the West of being behind a pair of daring bomb attacks that killed one nuclear scientist and wounded another in their cars on the streets of Tehran on Monday. He also admitted for the first time that a computer worm had affected centrifuges in Iran's uranium enrichment program.
Mahmoud Ahmadinejad and other Iranian officials vowed that the nuclear program would not be hampered by what they described as a campaign to sabotage it — whether by assassination or by the computer virus. The United States and its allies say Iran is seeking to build a nuclear bomb, a claim Tehran denies.
The two bomb attacks occurred when assailants on motorcycles attached magnetized bombs to the cars of two nuclear scientists as they drove to work in separate parts of the capital Monday morning. They detonated seconds later, killing one scientist, wounding another and wounding each of their wives, who were in the cars, Tehran's police chief said.
At least two other Iranian nuclear scientists have been killed in recent years, one of them in an attack similar to Monday's.
The wounded scientist, Fereidoun Abbasi, is on a list of figures suspected of links to secret nuclear activities in a 2007 U.N. sanctions resolution, which puts a travel ban and asset freeze on those listed. The resolution describes him as a Defense Ministry scientist who works closely with Mohsen Fakhrizadeh, believed to head secret nuclear projects. Iranian media said he was a member of the Revolutionary Guard, Iran's strongest military force.
Majid Shahriar, the scientist killed in the bombing, was involved in a major project with Iran's nuclear agency, said the agency's chief, Vice President Ali Akbar Salehi, though he did not give specifics.
"Undoubtedly, the hand of the Zionist regime and Western governments is involved in the assassination," Ahmadinejad told a news conference. He said the attack would not hamper the nuclear program.
In Washington, U.S. State Department spokesman P.J. Crowley said, "We decry acts of terrorism, wherever they occur. And beyond that, we do not have any information on what happened."
