US can intercept any Iran-linked ship globally, Caine says - Breaking Defense

Summary

WASHINGTON — As the US naval blockade of vessels in and out of Iranian ports enters day four, Chairman of the Joint Chiefs of Staff Gen. Dan Caine delivered a warning: Any vessel around the globe carrying supplies to or from Iran is a potential target. “The joint force, through operations and activities in other areas of responsibility, like the Pacific area of responsibility, under the command of Adm. [Samuel] Paparo, will actively pursue any Iranian flagged vessel or any vessel attempting to provide material support to Iran,” the four-star general told reporters this morning. “This includes dark fleet vessels carrying Iranian oil.” Caine did not disclose if the US military has boarded any such vessels yet outside of Central Command’s purview, though he did say no ships have been boarded as part of the blockade involving the Strait of Hormuz. His comments follow the April 8 announcement that Washington and Tehran reached a two-week ceasefire deal, with US President Donald Trump saying it was made on the condition that Iran agreed to reopen the Strait of Hormuz — a waterway where a fifth of the world’s oil transits through. However, as Israel continued its attacks on Hezbollah inside Lebanon, Iran cried foul and said vessels traveling through the waterway could become targets. That then prompted Trump to call for a US naval blockade to go into effect Monday morning for all vessels entering or departing Iranian ports and coastal areas, to include the Arabian Gulf and Gulf of Oman. Defense Secretary Pete Hegseth said approximately 10 percent of US naval power is now being used to enforce this. “This blockade applies to all ships, regardless of nationality, heading into or from Iranian ports,” Caine added today. “The US action is a blockade of Iran’s ports and coastline, not a blockade of the Strait of Hormuz. Enforcement will occur inside Iran’s territorial seas, and in international waters.” Caine explained that on Monday, CENTCOM was eyeing seven ships as possible blockade violators. In some cases, he added, a lead US ship, likely a destroyer, would move toward the suspected violator transmitting a message: “Do not attempt to breach the blockade. Vessels will be boarded for interdiction and seizure, transiting to or from Iranian ports. Turn around or prepare to be boarded. If you do not comply with this blockade, we will use force.” As of his briefing from the Pentagon this morning, Caine said the US military had not boarded another ship in the region.

Japan’s Defense Ministry said Friday that Iran used its geographical advantage to “inflict unbearable costs at a relatively low military expense,” effectively closing the Strait of Hormuz by indicating that it had laid naval mines, Kyodo News reported.

The ministry said Japan would strengthen its defense capabilities based on lessons from the US-Iran war, including by using defense equipment also operated by allies and like-minded partners to help ensure rapid supplies from other countries. It also stressed the need to maintain sufficient missile stockpiles and be prepared to quickly increase defense equipment production in an emergency, according to its first report analyzing the Iran war since February.

The US-Israeli war against Iran began on Feb. 28, with attacks targeting military, nuclear and infrastructure sites across the country. Iran responded with missile and drone strikes against Israel and US military facilities across the region. READ: EU joins US-led campaign to isolate Iran financially: Treasury chief Bessent Washington and Tehran signed a memorandum of understanding on June 18 concerning freedom of navigation through the Strait of Hormuz, but its implementation has stalled amid disagreements over security arrangements in the strait.

The Japanese report also said the country should take its own geographical characteristics into account when developing combat strategies, including the fact that it is surrounded by sea. The report noted the US use of AI to accelerate decision-making and operations, citing attacks on around 1,000 targets within 24 hours, while also highlighting the risk of AI making incorrect judgments.

“It is important to establish a process that maximizes the benefits of AI while ensuring appropriate human involvement,” the ministry said. The report comes ahead of a planned revision of Japan’s key security documents by the end of this year.

A major offensive by Yemen's Houthis to seize control of the gateway to the Red Sea has left more than 120 people dead, sources told AFP Friday, the country's deadliest clashes in years. Fighting erupted on Thursday, after the Iran-backed Houthis launched a ground assault along with rocket and drone attacks near coastal areas, vying for control of the narrow Bab al-Mandab strait at the Red Sea's southern entrance.

Yemen, embroiled in more than a decade of civil conflict, in July became the latest country to be drawn into the Middle East war as the Houthis upended a 2022 truce with the Saudi-backed government. Since then, the Houthis have imposed a maritime blockade of Saudi Arabia and repeatedly attacked its ships in the Red Sea -- a vital alternative route for oil exports after Iran all but halted Gulf shipments by blockading the Strait of Hormuz.

The rebels are now trying to tighten their hold over the Red Sea, one of the world's busiest shipping lanes, which they have disrupted with attacks on passing vessels since the Gaza war broke out in 2023. The Houthi offensive aims to cut off the government-held port city of Mokha, under fire for weeks, and advance towards areas bordering the Bab al-Mandab, military sources told AFP.

The rebels have seized elevated sites overlooking government positions near the Red Sea and the city of Taiz further inland, a military source and a Taiz official told AFP, requesting anonymity. The Houthis could target ships from these elevated positions, they said.

The toll rose to 129 on Friday, according to an AFP tally compiled from several sources, up from an earlier count of 81. A Yemeni military official speaking on condition of anonymity told AFP that 66 of his men had been killed, while medical and military sources close to the Houthis said at least 62 militants had died.

Another medical source said a civilian had also been killed. Although the Houthis do not control areas bordering Bab al-Mandab, they hold the key port city of Hodeida north of Mokha. "They are going for Bab al-Mandab," said Mohammed al-Basha, of the US-based risk advisory Basha Report.

The Houthis want to control the hills overlooking Bab al-Mandab and Mokha before attacking the coast, a Yemeni official in Aden, the government's base since it was ousted from the rebel-held capital, Sanaa, in 2014. The government has sent reinforcements to Taiz from Aden on Saudi orders, he said.

"The Houthis feel that if they capture Bab al-Mandab or Mokha port they will be in a better position of power to negotiate with the government and the Saudis," Basha added. With Iran's closure of Hormuz, the Bab al-Mandab chokepoint has gained increased importance as a transit route for oil from Saudi Arabia, the world's biggest exporter of crude.

The narrow waterway connects the Red Sea -- and, via the Suez Canal, the Mediterranean -- to the Indian Ocean. In July, a fragile truce between the Houthis and the government fell apart after the rebels welcomed an Iranian plane to Sanaa, setting off a spate of attacks.

They later announced a maritime blockade of Saudi Arabia and began hitting its ships and territory.

If passed, the resolution would follow up on one adopted on June 12 of last year declaring Iran in breach of its non-proliferation obligations for not fully cooperating with an investigation into uranium traces found at undeclared sites. Israel started bombing Iran's nuclear facilities the next day, soon joined by the U.

S. Iran's uranium-enrichment plants were destroyed or badly damaged. Iran has not let International Atomic Energy Agency inspectors return to the bombed sites since then or verify what remains of its stocks of enriched uranium, some of which was enriched to up to 60% purity, a short step from weapons grade.

FRESH DIPLOMATIC ESCALATION A resolution by the IAEA's 35-nation board reporting Iran to the Security Council would also be the culmination of a standoff over IAEA access to those sites, since the board has passed two resolutions in the past year demanding Iran declare its enriched uranium stocks and grant the IAEA full access to verify them.

"(The board) requests the (IAEA) Director General to transmit this resolution and the previously adopted resolutions ... to all Members of the Agency and to the Security Council and the General Assembly of the United Nations," said the latest resolution draft seen by Reuters.

It also "reiterates its call upon Iran to urgently remedy its non-compliance with its Safeguards Agreement by taking all steps deemed necessary by the Agency and the Board, so that the Director General can provide the necessary assurances regarding the correctness and completeness of Iran's declarations".

The draft has not yet been formally submitted to the board and negotiations over the exact wording are ongoing, diplomats said. Whenever the four powers have submitted a draft resolution on Iran in recent years, it has passed. Concrete action by the Security Council against Iran is unlikely since Tehran's allies Russia and China are permanent, veto-wielding members.

IAEA CONCERNS OVER ENRICHMENT Iran has often retaliated following IAEA board resolutions against it by escalating its nuclear activities or scaling back cooperation with the IAEA, but its options for both are currently extremely limited. It is unclear what other repercussions there might be on Tehran's conflict with the U.

S. As a party to the nuclear Non-Proliferation Treaty (NPT), Iran has the right to develop nuclear technology, including enrichment, for peaceful purposes. Iran says it would never produce nuclear weapons. It is, however, the only country to enrich to 60% without making a bomb.

The IAEA has said the amount it has enriched to that level is of serious concern. The IAEA estimates Iran had 440.9 kg of uranium enriched to that level before its sites were bombed. That is enough, if enriched further, for 10 nuclear weapons, according to an IAEA yardstick.

The US and its allies Britain, France and Germany are pushing other countries on the UN nuclear watchdog's board to pass a resolution next week reporting Iran to the UN Security Council for the first time in 20 years, diplomats said on Friday. If passed, the resolution would follow up on one adopted on June 12 of last year declaring Iran in breach of its non-proliferation obligations for not fully cooperating with an investigation into uranium traces found at undeclared sites.

The US launched an air war against Tehran on February 28 in which, together with Israel, it destroyed or badly damaged Iran's uranium-enrichment facilities. Iran has not let International Atomic Energy Agency (IAEA) inspectors return to the bombed sites since then or verify what remains of its stocks of enriched uranium, some of which was enriched to up to 60% purity, a short step from weapons grade.

Resolution would be culmination of standoff over IAEA's access to nuclear sites A resolution by the IAEA's 35-nation board reporting Iran to the Security Council would also be the culmination of a standoff over IAEA access to those sites, since the board has passed two resolutions in the past year demanding Iran declare its enriched uranium stocks and grant the IAEA full access to verify them.

A draft text for the resolution has yet to be formally submitted to the board and negotiations between countries over the exact wording are ongoing, diplomats said. A draft is usually formally submitted early in the week of a board meeting. As a party to the nuclear Non-Proliferation Treaty (NPT), Iran has the right to develop nuclear technology, including enrichment, for peaceful purposes.

Iran says it would never produce nuclear weapons. It is, however, the only country to enrich to 60% without making a bomb. The amount it has enriched to that level is "a matter of serious concern" to the IAEA. The IAEA believes well over 200 kg of that highly enriched uranium has survived the bombardments and is held in a tunnel complex at Isfahan and at the Natanz facility.
