Tehran has warned that it will retaliate against the United States by targeting its regional infrastructure if US President Donald Trump proceeds with his threat to attack Iran's power plants, according to a military spokesperson.

“If Iran’s fuel and energy infrastructure is attacked by the enemy, all energy, information technology, and desalination infrastructure belonging to the United States and the regime in the region will be targeted,” a spokesperson for Iran’s Khatam al-Anbiya Central Headquarters said, Mehr reported on Sunday.

Hours earlier, Trump threatened to “hit and obliterate” Iranian power plants if Tehran does not reopen the Strait of Hormuz within 48 hours.

Trump posted his warning on Truth Social at 7:44 p.m. ET on Saturday, which means his deadline expires at 7:44 p.m. ET on Monday.
