Unknown to most Iranians until Friday, when he was assassinated, the nuclear scientist Mohsen Fakhrizadeh was well known to those who followed Iran’s nuclear programme. Western security sources regarded him as instrumental in it.
Iranian media downplayed Fakhrizadeh’s importance, introducing him as a scientist and researcher involved in the search for “homegrown test kits for Covid-19” in recent weeks.
Mark Fitzpatrick, an associate fellow with London’s International Institute for Strategic Studies who follows Iran’s nuclear programme closely, also tweeted: “Iran’s nuclear program is long past the point when it is dependent on a single individual“.
Yet we know that when he was attacked Fakhrizadeh was accompanied by several bodyguards, indicating how seriously Iran took his security.
