Iran's top nuclear scientist was assassinated by a remote-controlled machine gun placed in the back of another car, the country's media says

 On Friday, Mohsen Fakhrizadeh was assasinated while driving with his wife and security convoy in the Iranian city of Absard, near Tehran. The Iranian defense ministry has given few details of the killing but has pointed the finger at Israel.

New information about the attack was reported Sunday, however, with Fars saying Fakhrizadeh stopped and left his car after mistaking several bullets that had just hit his vehicle for engine trouble.

At this point, Fars said, a Nissan pickup truck stopped 150 meters, or about 492 feet, from Fakhrizadeh, and a gun mounted on the back of the truck opened fire, hitting him twice in the back and once in the spine.

Three security cars had been traveling with Fakhrizadeh, and a bodyguard who launched himself over the scientist's body was also shot, Fars reported.

According to Fars, after the hit on Fakhrizadeh was complete, the Nissan truck exploded. The entire attack lasted three minutes, the news agency reported.

Investigations have indicated the registered owner of the Nisan left Iran on Sunday, Fars reported, without citing the person's identity.

On Monday, the day of Fakhrizadeh's funeral, Iran's top national security official, Ali Shamkhani, told reporters the assassination was "conducted using electronic equipment and there was nobody on the scene," . .

Iran has blamed Israel for the attack, with Shamkhani saying on Monday that the People's Mojahedin Organization of Iran, a militant group that opposes the Iranian government, was also involved.

Another popular narrative about the killing circulating in Iranian media is that Fakhrizadeh was killed by a team of 12 assassins who were part of a 62-person hit squad
