Iran's Foreign Ministry spokesperson Esmaeil Baghei said on Monday that, should a UN nuclear watchdog make a resolution against Iran, Tehran will retaliate.

He said that European states are 'irrational' for seeking a UN resolution against Iran when 'imposed-war' made nuclear facilities inaccessible.

He further said the conflict with the US was not a war, but "overt aggression."

This is a developing story.
