Iran’s national security chief said the architect behind Iran’s military nuclear program, who was assassinated last week, was killed remotely by Israel through “electronic devices.”

Ali Shamkhani, the secretary of Iran’s Supreme National Security Council, made the allegation at the funeral of the murdered scientist, Mohsen Fakhrizadeh. Often referred to as the Robert Oppenheimer of Iran, the Fakhrizadeh was killed in Absard, to the east of Tehran, on Friday in broad daylight.
