After Iran's missile attack on Israel on Oct. 1, there has been speculation that Israel could strike Iran's nuclear facilities, as it has long threatened to do.

"We have always taken these threats seriously," Kamalvandi said. 

Prime Minister Benjamin Netanyahu's office said in a statement on Tuesday that Israel would listen to the United States but would decide its actions according to its own national interest.

The statement was attached to a Washington Post article which said Netanyahu had told President Joe Biden's administration that Israel would strike Iranian military targets, not nuclear or oil targets.

Biden has said he would not support an attack on Iran's nuclear sites and oil markets have been on edge over the prospect of an Israeli strike against Iranian oil fields.

Kamalvandi told Nournews that any attack on Iran's nuclear sites remained improbable and that if this happened, the damage was likely to be minimal and quickly repaired by Iran. 

"We have planned in a way that if they commit any stupidity, the damages would be minimal," Kamalvandi said. 

The Iranian spokesperson added that the UN nuclear watchdog and the international community should condemn any threat or attack on nuclear sites.
