On Sunday, parliament said the “best response” to Fakhrizadeh’s assassination would be to “revive Iran’s glorious nuclear industry” by halting the voluntary implementation of the additional protocol, a document which under the 2015 accord prescribes more intrusive inspections of Iran’s nuclear facilitates.

In a statement following its meeting, the legislature said the killing showed that Israel, the US and their allies had become “brazen” in their “terror and sabotage” against Iran.

But the spokesman for Iran’s atomic energy organisation, Behrouz Kamalvandi, told IRNA on Saturday that the issue of inspectors’ access “must be decided on at high levels” of the Islamic republic’s leadership.
