text: Tehran, Iran (CNN) -- A nuclear scientist was killed in a blast in Tehran on Wednesday morning, an Iranian news agency reported, in the latest in a string of attacks that Iran has blamed on Israel. 
  
  A motorcyclist placed a magnetic bomb under Mostafa Ahmadi Roshan's Peugeot 405, the state-run IRNA news agency said. The blast also wounded two others, IRNA said. 
  
  State television channel Press TV reported later Wednesday that Roshan's driver, Reza Qashqaei, had died in a hospital from his injuries. 
  
  Mohammad Khazaee, Iranian ambassador to the United Nations, condemned what he called "cruel, inhumane and criminal acts of terrorism against the Iranian scientists." 
  
  "Based on the existing evidence collected by the relevant Iranian security authorities, similar to previous incidents, perpetrators used the same terrorist method in assassinating Iranian nuclear scientists, i.e., attaching a sticky magnetic bomb to the car carrying the scientists and detonating it," Khazaee said in a statement. 
  
  "I would like to emphasize, once again, that the Islamic Republic (of) Iran would not compromise over its inalienable right to use nuclear energy for peaceful purposes and any kind of political and economic pressures or terrorist attacks targeting the Iranian nuclear scientists, could not prevent our nation in exercising this right," Khazaee said. 
  
  Lawmaker Kazem Jalali blamed the intelligence agencies of the United States and Israel for the latest attack, saying the United Nations' nuclear watchdog, the International Atomic Energy Agency, also bore responsibility for passing on information about Iran's nuclear scientists to other countries, IRNA reports.
