The Jewish Chronicle reported that the Iranian nuclear scientist Mohsen Fakhrizadeh, who was assassinated in November near Tehran, was killed by a weapon weighing a ton, smuggled into Iran by the Israeli intelligence service (Mossad), after dismantling it into several parts .

Reuters quoted the British Jewish newspaper website as saying that a group of more than 20 agents, including Israeli and Iranian citizens, ambushed the scientist Fakhri Zadeh after observing him for 8 months.

Reuters was not able to confirm the report, which was published on Wednesday on the London-based newspaper's website.

Iranian media reported that Fakhrizadeh, 59, died in hospital, after gunmen shot him in his car.

Shortly after his death, Iran pointed the finger of accusation at Israel, and Foreign Minister Muhammad Javad Zarif wrote on Twitter saying, "Serious evidence of an Israeli role."

The newspaper - which is the oldest Jewish newspaper in the world - said that the Mossad installed an automatic weapon on a pickup truck, indicating that the weapon - which was controlled by remote agents while monitoring the target - was very heavy, because it contained a bomb that destroyed it. Evidence after the killing. "

The newspaper’s report says that Iran “secretly estimated that it would take 6 years” before a replacement for Fakhrizadeh was available “at full capacity,” and that his death “extended the period of time needed by Iran to build a bomb from about 3.5 months to two years.”

He added that the attack was carried out by "Israel alone, without American intervention," but he made clear that the American officials had received prior notice of the matter.

Israel declined to comment in November, and an Israeli government spokesman responded on Wednesday to the latest report by saying, "We never comment on such matters. There has been no change in our position."

For years, Western and Israeli intelligence agencies have described Fakhrizadeh as the mysterious person responsible for a secret atomic bomb program that was stopped in 2003, and Israel and the United States accuse Tehran of trying to restore it, but Tehran has always denied its pursuit of converting nuclear energy into military.
