Seyed Ali Mousavi, Iran’s envoy to the International Maritime Organization, said in remarks carried by two Iranian news agencies that navigating the strait is possible for “everyone except enemies” — indicating Tehran would determine which vessels are allowed passage. Iran has already approved the passage of ships through the waterway to China and elsewhere in Asia.

Israel’s military said it was not able to intercept missiles that hit Dimona and Arad on Saturday, the largest cities near the Negev Desert nuclear center. It was the first time Iranian missiles penetrated Israel’s air defense systems in the area.

“If the Israeli regime is unable to intercept missiles in the heavily protected Dimona area, it is, operationally, a sign of entering a new phase of the battle,” Iran’s Parliament Speaker Mohammad Bagher Ghalibaf said on X.

Rescue workers said at least 64 people were taken to hospitals after the direct hit in Arad. Dimona is about 20 kilometers (12 miles) west of the nuclear research center and Arad around 35 kilometers (22 miles) north.

Israel’s hard-line national security minister, Itamar Ben-Gvir, visited Arad on Sunday, saying that Israel is in a “historic battle” against Iran and that it must “continue until victory.”

Israel is believed to possess nuclear weapons, though it doesn’t confirm or deny this. The U.N. nuclear watchdog said on X it had not received reports of damage to the Israeli center or any abnormal radiation levels.

Tehran’s main nuclear enrichment site at Natanz was hit earlier on Saturday. Israel denied responsibility for the attack and the Iranian judiciary’s official news agency, Mizan, said there was no leakage.

The Pentagon declined to comment on the strike on Natanz, which was also hit in the first week of the ongoing war and in the 12-day war last June.

The U.N. watchdog — the International Atomic Energy Agency — has said the bulk of Iran’s estimated 972 pounds (441 kilograms) of enriched uranium is elsewhere, beneath the rubble at its Isfahan facility.

The U.S. and Israel have offered shifting rationales for the war, from hoping to foment an uprising that topples Iran’s leadership to eliminating its nuclear and missile programs and its support for armed proxies. There have been no signs of an uprising, while internet restrictions limit information from Iran.

The war’s effects are felt far beyond the Middle East, raising food and fuel prices.

So far in Iran, the death toll in the war has surpassed 1,500, the state broadcaster reported Saturday, citing the health ministry. In Israel, 15 people have been killed by Iranian missiles. Four others have died in the occupied West Bank. At least 13 U.S. military members have been killed, along with well over a dozen civilians in Gulf nations.
