Iran’s most senior nuclear scientist Mohsen Fakhrizadeh has been assassinated near the capital Tehran, the country’s defence ministry has confirmed.
Fakhrizadeh died in hospital after an attack in Absard, in Damavand county.
Iran’s Foreign Minister Mohammad Javad Zarif, has condemned the killing “as an act of state terror”.
Western intelligence agencies believe Fakhrizadeh was behind a covert Iranian nuclear weapons programme.
“If Iran ever chose to weaponise (enrichment), Fakhrizadeh would be known as the father of the Iranian bomb,” one Western diplomat told Reuters news agency in 2014.
In a statement on Friday, Iran’s defence ministry said: “Armed terrorists targeted a vehicle carrying Mohsen Fakhrizadeh, head of the ministry’s research and innovation organisation.
“After a clash between the terrorists and his bodyguards, Mr Fakhrizadeh was severely injured and rushed to hospital.
“Unfortunately, the medical team’s efforts to save him were unsuccessful and minutes ago he passed away.”
