State Department tells Americans worldwide to 'exercise increased caution'

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."

15 people were injured in an Iranian missile attack in the Tel Aviv area Sunday, according to Israel Fire and Rescue.

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.

The Iranian military said on Sunday that Tehran would seek to retaliate against U.S. energy sites and infrastructure in the Gulf region if Washington moves to strike Iranian power plants, according to Fars News Agency, a semi-official state news agency affiliated with Iran’s Islamic Revolutionary Guard Corps.

Trump said on Saturday that the U.S. would "hit and obliterate" Iranian power plants if the Strait of Hormuz wasn’t opened within 48 hours

"If Iran’s fuel and energy infrastructure is attacked by the enemy, all energy infrastructure, as well as information technology (IT) and water desalination facilities, belonging to the U.S. and the regime in the region will be targeted pursuant to previous warnings," said Lt. Col. Ebrahim Zolfaqari, a spokesperson for the Iranian Armed Forces, according to Fars.
