According to the paper, Israeli special ops planned the killing over a period of many months, and observed Mostafa Ahmadi-Roshan from a control room in a safe house in Tehran as the scientist prepared to leave for work on the morning of his death.
Roshan was killed when a masked person on a motorbike planted a bomb on his car as his bodyguard drove him to Natanz uranium enrichment site, where he served as director.
Hundreds of regime supporters swore to avenge the scientist’s death at Roshan’s funeral on Friday, it is reported.
The US has categorically denied any involvement with the alleged plot.
Secretary of Defence Leon Panetta said: “We were not involved in any way with regards to the assassination that took place there.”
Iranian officials last week accused Israel of carrying out terrorist attacks against Tehran, citing the killings of several nuclear scientists over the past two years.
