Washington. US President Donald Trump is hardening his threats to strike Iran’s critical infrastructure if the government in Tehran doesn’t reopen the Strait of Hormuz by his Monday deadline.

In a profanity-laced social media post Sunday, Trump says Tuesday will be “Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it.”

His direct message to Iran’s leaders is, “Open the F------ Strait, you crazy b-------, or you’ll be living in HELL – JUST WATCH.”

The Republican president has threatened widespread destruction of Iran’s energy resources and other vital infrastructure, potentially including desalination plants that supply drinking water, if the vital waterway doesn’t reopen.

Earlier in the day, Iran’s joint command also threatened to step up its attacks on oil and other civilian infrastructure facilities if the US and Israel attack Iranian civilian facilities.

Iran’s state-run news agency quoted the Khatam al-Anbiya Headquarters as saying that it had attacked a number of oil and other infrastructure facilities in Israel and in Gulf Arab countries after an Israeli airstrike struck Iran’s largest petrochemical complex.

“We once again repeat: if you commit aggression again and strike civilian facilities, our responses will be more forceful,” the IRNA news agency quoted a spokesman.

Iran also claimed on Sunday that it had destroyed four US aircraft during the complex rescue of an airman whose fighter jet was shot down on Friday.

Iran's state TV quoted the Khatam al-Anbiya Headquarters as saying the aircraft, which included two C-130 military transport aircraft and two Black Hawk helicopters, were destroyed in the province of Isfahan, where the rescue took place.

Earlier Sunday, Iran’s state TV aired a video showing what it claims are parts of a US aircraft that they had shot down and a photo of thick black smoke rising into the air.

The claims could not be independently verified.

The United Arab Emirates, meanwhile, reported attacks with dozens of missiles and drones from Iran. The Defense Ministry said that among the 60 projectiles fired at the country were nine ballistic missiles, 50 drones, and one cruise missile.

This brings the total number of projectiles that have targeted the UAE during the war to 507 ballistic missiles, 24 cruise missiles, and 2,191 drones.

In Kuwait, drone attacks ignite fires at oil and petrochemical facilities. The Kuwait Petroleum Corporation described the damage caused as “significant.”
