Iran on Wednesday dismissed allegations that it is operating a secret nuclear facility inside Kolang Mountain, insisting the location has no nuclear-related activities despite renewed threats from United States President Donald Trump to target the area.
The latest exchange comes amid heightened tensions between Washington and Tehran following Trump’s warning that the United States could launch military strikes against the mountainous site located in central Iran.
Responding to the allegations, Iranian Foreign Ministry spokesman Esmaeil Baqaei accused the United States of manufacturing claims about the location as a justification for further military action against 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,” Baqaei wrote on X.
The spokesman maintained that Iran has remained transparent about its nuclear programme and continues to declare all of its nuclear activities to the International Atomic Energy Agency (IAEA), the United Nations‘ nuclear watchdog.
He reiterated that there is no undisclosed nuclear installation at the mountain, rejecting suggestions that Iran is secretly expanding its nuclear infrastructure.
“Iran’s nuclear activities have been fully declared,” he added.
Trump had intensified pressure on Tehran during remarks on Tuesday, warning that the United States was prepared to strike the area known internationally as Pickaxe Mountain.
“We’ll be hitting that area pretty soon, and very heavily,” Trump said.
The US president added that he would ordinarily avoid publicly announcing potential military targets but insisted, “there’s not a thing they can do about it.”
Despite the warning, Washington has not carried out any military operation against the site as of Wednesday.
Claims about alleged underground nuclear construction at Kolang Mountain have circulated for more than a year.
In 2025, several American media organisations, including The Washington Post and The New York Times, reported that Iran had significantly accelerated construction work at what they described as a secret underground nuclear complex inside the mountain.
Iran strongly rejected those reports at the time, insisting they were inaccurate and politically motivated.
Kolang Mountain is located close to Iran’s Natanz nuclear facility, one of the country’s most prominent uranium enrichment centres.
Natanz itself became a major focus of international attention after it was bombed by the United States during the brief conflict between Washington and Tehran in June 2025.
The renewed dispute over Kolang Mountain comes as international concern continues over Iran’s nuclear programme and the possibility of further military escalation between the two countries.
