An Iranian nuclear scientist was killed and another injured when they and their wives were attacked by "terrorists" on Monday, state television and other media reported.
  
"In a criminal terrorist act, the agents of the Zionist regime attacked two prominent university professors who were on their way to work," the website of Iran's state television network reported, referring to Israel. "Dr. Majid Shahriari was killed and his wife was injured. Dr. Fereydoon Abbasi and his wife were injured," the report said according to AFP.
  
Fars news agency said the scientists were targeted in two different locations by men on motorcycles who approached their vehicles and attached bombs to their cars.
  
According to the official IRNA news agency, Shahriari was a member of the nuclear engineering department of Shahid Beheshti University in northern Tehran.
  
The news website Mashreghnews said Abbasi held a PhD in nuclear physics and did nuclear research at the defense ministry.

Al Jazeera's Alireza Ronaghi, reporting from Tehran, said the victim was a colleague of another professor, Massoud Ali-Mohammadi, who was killed in January in the same way.

Iran's atomic chief warned "enemies" of the Islamic Republic they were "playing with fire" after the killing, mainly blamed on Israel, of Shahriari. "Don't play with fire. Iranians' patience is limited and if their patience runs out, our enemies will have a bad fate," Ali Akbar Salehi was quoted as saying by the state news agency IRNA.

"Dr. [Majid] Shahriari was my student for years and he had good cooperation with the Atomic Energy Organization. He was in charge of one of the great projects of the organization," he said. "We will boost the nuclear movement of the Iranian nation by several times," he added.
