State Department tells Americans worldwide to 'exercise increased caution'

Iranian Foreign Minister Seyed Araghchi on Sunday reiterated the Iranian message that the Strait of Hormuz "is not closed" as President Trump imposed a deadline for Iran to stop its attacks on the strait or face strikes on energy infrastructure.

"Strait of Hormuz is not closed. Ships hesitate because insurers fear the war of choice you initiated — not Iran," Araghchi wrote on X. "Ships hesitate because insurers fear the war of choice you initiated — not Iran. No insurer — and no Iranian — will be swayed by more threats. Try respect."

"Freedom of Navigation cannot exist without Freedom of Trade. Respect both — or expect neither," Araghchi further said in his Sunday post.

"If Iran doesn’t FULLY OPEN, WITHOUT THREAT, the Strait of Hormuz, within 48 HOURS from this exact point in time, the United States of America will hit and obliterate their various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST!" Trump said in a post on his social media platform Saturday.

The Strait of Hormuz is open to everyone aside from Tehran’s "enemies," Iran’s representative to the International Maritime Organization, Ali Mousavi, told the semi-official Mehr News Agency on Sunday.

"Passage of ships through the Strait of Hormuz is possible with coordination for security and safety arrangements," Mousavi told Mehr in an interview published on Sunday.

"Iran is ready to cooperate with the IMO and countries to improve maritime safety and protect mariners," Mousavi said, according to the report.

Later Sunday, Iranian President Masoud Pezeshkian echoed that statement in a post on X, saying in part "the Strait of Hormuz is open to all except those who violate our soil. We firmly confront delirious threats on the battlefield."

In weeks since the joint U.S. and Israeli attacks on Iran began, Tehran has claimed attacks on several ships transiting through the strait and in the gulfs on either side of it.

During a visit Sunday to the site of an Iranian missile strike in Arad, in southern Israel, Israeli Prime Minister Benjamin Netanyahu said the strikes were "proof that Iran endangers the entire world."

“If you want proof that Iran endangers the entire world, the last 48 hours have given it. In the last 48 hours, Iran targeted a civilian area. They're doing that as a mass murder weapon. Luckily, no one was killed, but that's due to luck, not their intention. Their intention is to murder civilians," Netanyahu said.

Netanyahu also noted Friday morning's reported launch of two ballistic missiles at a joint U.S.-U.K. military base on the island of Diego Garcia, in the Indian Ocean, some 2,000 miles south of Iran. Neither of the missiles struck the base, nor is it clear how far the missiles traveled.

"I've been warning all the time. They have now the capacity to reach deep into Europe," Netanyahu said, in part. "They are putting everyone in their sights."

"What more proof do you need that this regime that threatens the entire world has to be stopped?" Netanyahu said. "Israel and the United States are working together for the entire world. And it's time to see the leaders of the rest of the countries join up."

One of the injured is in moderate condition while the rest suffered mild injuries, emergency services officials said.

According to Israel Fire and Rescue there were several similar scenes across central Israel, including a vehicle that was hit as well as a hit on a building in Tel Aviv. There were also strikes on several locations in surrounding cities, officials said.
