Iran Warns of Devastating Response if US Attacks Underground Facility Amid Rising Tensions

A senior security source in Tehran warned on July 12, 2026, that Iran will deliver a "devastating response" if US President Donald Trump follows through on his threat to attack the underground maintenance facility known as "Mount Peakax." The source stated that American soldiers and US allies in the region would bear the consequences of such an attack. The Iranian official also denied US claims that nuclear activity is taking place at the site.

Regarding the Strait of Hormuz, which Iran announced it would close over the weekend, the source emphasized that Tehran will not back down from defending the rights of the Iranian people. He added that whether or not Trump attacks the facility, it will not affect Iran's enforcement of its arrangements in the Strait.

Tensions between the US and Iran escalated as the US military launched a new wave of strikes against Iranian targets for the third consecutive night, raising fears that a memorandum of understanding aimed at ending the conflict might collapse. Earlier, Trump threatened Iran with powerful strikes over the next two to three weeks, criticizing Tehran for failing a test related to the memorandum.

Reports from Iran indicated a series of explosions in the south of the country, including Bandar Abbas, Larak Island, Qeshm Island, and the Strait of Hormuz. Concurrently, Reuters cited security sources reporting a missile attack on a site belonging to an Iranian-Kurdish opposition group east of Erbil in Iraq.
