Israel's Mossad assassinated an Iranian scientist in a bomb attack, Time Magazine reported, citing unnamed Western intelligence sources.
The report Saturday came as Iranian state television reported that the Islamic Republic had evidence that the United States was behind the Jan. 11 attack, that it said was "planned, guided and supported" by the Central Intelligence Agency.
The Time report also intimated that Israel was behind the deaths of three other Iranian nuclear scientists in the last two years.
Israel has neither confirmed nor denied ties to the assassinations.
On Sunday, Iran's deputy armed forces chief, Brig.-Gen. Massoud Jazayeri, vowed in an interview with the state-run Press TV to retaliate against Israel for its role in the assassination.
“The opponents of Revolution and the nation's progress should have no doubt that the punitive response to the US, the Zionist regime and their criminal accomplices will be delivered in an opportune time,” he reportedly said.
