Iran has blamed Israel for the Nov. 27 killing of Mohsen Fakhrizadeh, who was seen by Western intelligence services as the mastermind of a covert Iranian nuclear weapons programme.
Iran has blamed Israel for the assassination of top nuclear scientist Mohsen Fakhrizadeh.
Israel has neither confirmed nor denied responsibility for the killing, but in the past has acknowledged pursuing covert, intelligence-gathering operations against the nuclear programme of its arch-enemy Iran.
Fakhrizadeh died on Friday after being seriously wounded when assailants targeted his car and engaged in a gunfight with his bodyguards outside Tehran, according to Iran's defence ministry.
Iran's President Hassan Rouhani has accused arch-foe Israel of acting as a US "mercenary" and killing Mohsen Fakhrizadeh when assailants opened fire at him and his bodyguards near Tehran on Friday.
