Trump says we're 'blowing up the whole country' if Iran doesn't make deal in 48 hours

The Iranian government has responded to President Donald Trump's threat of "blowing up the whole country" if the regime fails to open up the Strait of Hormuz by Tuesday evening.

"Iran's reaction would be one of reciprocating any such attack," Iranian Foreign Ministry spokesperson Ismail Baghaei said in a statement on Sunday afternoon. "Our armed forces have made it clear that in case Iran's infrastructure is attacked, we would react in kind."

Baghaei said that if the United States carries out Trump's threat, Iranian forces would "target similar infrastructure that is owned or in any way or manner related to the United States or contributes to their act of aggression against Iran."

Earlier Sunday, Trump told ABC News that if Iran doesn't strike a peace deal, including opening up the critical Strait of Hormuz, "we're blowing up the whole country."

Also, in a post on his social media platform on Sunday, Trump said, "Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!!"

The Iranian Mission to the United Nations also released a statement in reaction to Trump's statements, saying, the president "openly threatens to destroy infrastructure essential to civilian survival in Iran."

"If the conscience of the United Nations were alive, it would not remain silent in the face of the overt and shameless threat by the war-mongering President of the United States to target civilian infrastructure. Trump seeks to drag the region into an endless war," the Iranian Mission to the United Nations said in a statement. "This is direct and public incitement to terrorize civilians and clear evidence of intent to commit war crimes."

The Iranian Mission said the "international community and all States have obligations to prevent such atrocious acts of war crimes."

"They must act now. Tomorrow is too late," the Iranian Mission's statement said.

Iran and Oman are in active talks to manage and potentially reopen maritime traffic through the Strait of Hormuz, which has been heavily restricted since the war began on Feb 28, the two countries said on Sunday.

Officials from both sides met on Saturday to discuss practical options, according to the Omani Ministry of Foreign Affairs.

"The meeting discussed possible options for ensuring smooth passage through the Strait of Hormuz during the circumstances witnessed in the region," the Omani Ministry of Foreign Affairs said in a statement.

Iranian Foreign Minister Abbas Araghchi told Al Jazeera that Iran is working on a joint protocol with Oman to "monitor" and "supervise" transit through the strait under wartime conditions.

Iranian officials are also stressing that decisions on the strait should be handled jointly by Tehran and Oman, pushing back on outside involvement.

News of the discussions came as pressure builds from the United States, including Trump’s 48-hour ultimatum for Iran to open the strait by 8 p.m. ET on Tuesday and growing concerns over global oil supply disruptions.

U.S. Central Command (CENTCOM) on Sunday said that the F-15 fighter jet with two crew members aboard was shot down on Thursday over Iran.

"On April 4, U.S. forces successfully completed the rescues of two American service members from Iran after their F-15E fighter jet was shot down April 2 during a combat mission," CENTCOM said in a statement.

CENTCOM confirmed that the two service members, whose names have not been released, were "safely recovered during separate search and rescue missions."

U.S. strikes into Iran continue as CENTCOM "forces dismantle the Iranian regime’s ability to project power beyond its borders," according to the CENTCOM statement.

A missile hit a seven-story residential building in the northern Israeli port city of Haifa on Sunday, causing "extensive damage" and injuring several people, according to Israel's national emergency service Magen David Adom (MDA).

Among the wounded was an 82-year-old man in serious condition who was injured by a heavy object and the blast, the MDA said. Three other people suffered injuries from shrapnel and the blast, and five people were treated for anxiety symptoms, according to the MDA.

The MDA said the building "sustained a direct hit" and that search and rescue crews remain at the scene.

United Hatzalah, an Israeli volunteer-based emergency service that also deployed to the scene, said one building had collapsed and another had partially collapsed. Teams were searching for people potentially trapped in the rubble, according to United Hatzalah.

It was not immediately clear where the missile originated.
