Iran again denied the existence of any secret nuclear complex at Kolang mountain on Wednesday, after US President Donald Trump threatened to strike the site in the centre of the country.

“Washington’s obsessive focus on Kolang Kouh where no nuclear activity is taking place is nothing more than a fabricated pretext for aggression, destruction, and sabotage,” Iranian foreign ministry spokesman Esmaeil Baqaei said on X.

He insisted “Iran’s nuclear activities have been fully declared” to the UN’s atomic watchdog.

Trump had warned on Tuesday that the US would hit the site, known as Pickaxe Mountain in English.

“We’ll be hitting that area pretty soon, and very heavily,” Trump said, adding that he would not normally announce targets but “there’s not a thing they can do about it”.
