More Iran Nuclear Sites Targeted; UAE Presses for Hormuz Security Force

The United Arab Emirates, which has been among the hardest-impacted Gulf states in Iran’s ongoing retaliation, is pressing for a multinational maritime ​taskforce to reopen vital oil transit waterway, the Financial Times reports ‌Friday.

The UAE, with a navy that’s not really going to strike fear into any enemy (much less the Iranians), says it is willing to participate in a “Hormuz Security Force” to defend the strait and escort shipping. Dozens of countries are being asked to join, sources cited in FT say. So far there have been no takers. Meanwhile, more alarming escalation with fresh US-Israeli attacks on nuclear sites, as Tehran threatens to launch revenge attacks in kind (on Gulf and Israel):

• IRAN SIGNALS POSSIBLE ATTACKS ON STEEL FACTORIES IN GULF AND ISRAEL, ACCORDING TO TASNIM.
• Aardakan yellow cake factory (nuclear) in Yazd province attacked by US and Israeli Friday evening (local)
• No radiation leak detected, local authorities say

Tasnim says that Iran’s response will “not be limited to the region’s steel industries” and that a “broader more severe response” is on the agenda. And…

The IDF announces the following [machine translation]:

After identifying rehabilitation attempts: The Air Force struck the heavy water plant in Arak – a key infrastructure for producing plutonium for nuclear weapons With precise guidance from Military Intelligence, the Air Force struck a short while ago the heavy water plant in Arak, located in central Iran. Heavy water is a unique material used to operate nuclear reactors such as the currently inactive reactor in Arak, which was originally designed to have the capability to produce weapons-grade plutonium. These materials are also used as a source for extracting neutrons for nuclear weapons.

Vital Iranian Steel Plants, Industry Attacked

Israeli media citing military officials on Friday: “The IDF attacked Iran’s two largest steel plants, in Isfahan and Ahvaz. Both plants are vital to Iran’s military industry and are partially owned by the Revolutionary Guards. The strikes on the plants are expected to cause billions in damage to the Iranian economy.”

This could mark a new, expanded phase of the war as Israel goes after key defense industrial targets, which also serve central civilian infrastructure development. The US has still held off on pursuing more attacks on energy sites, but it seems Israel is maintaining a more gloves off approach – opting for total societal destruction, and going after industry. This seems to also be part of efforts to ensure ballistic missile production is degraded. 

Reuters: US is certain about having destroyed third of Iran’s missiles, say sources. Another third is believed to be damaged, destroyed or buried.

Also, Khondab Heavy Water Research Reactor, part of the Arak Nuclear Complex, targeted.

Reports from Iran suggest that all three of Iran’s largest steel production plants were struck in a coordinated targeted strikes.

“One of the sources said the intelligence was similar for Iran’s drone capability, saying there was some degree of certainty about a third having been destroyed,” Reuters writes, noting that all of this contradicts White House claims of Iran having “very few rockets left”.

Iran Didn’t Request Trump’s 10-Day Pause: WSJ

Iran has not requested a 10-day pause on strikes on its energy plants, peace talk mediators have been cited in WSJ as saying, and has still not issued formal response to the 15-point US plan delivered via Pakistan. This as the Pentagon is moving thousands of Marines and Army Airborne soldiers into the region.

The Wall Street Journal points out that “The U.S. and Israel are pounding Iran’s missile-launching sites, hitting some over and over across almost a month of war. But Tehran’s missiles keep flying.”

One pundit questions, are we ‘winning’ yet?… writing the following brief assessment of where things stand: IRGC Joint Staff headquarters under US-Israeli strikes. Iran naming UAE targets as Abu Dhabi enters the war. IDF Chief of Staff warning publicly the Israeli military could “collapse” from manpower shortages. Iran claiming over one million fighters mobilised with IRGC lowering the age for support roles to 12. Pentagon considering 10,000 additional ground troops within striking distance of Kharg. Trump pausing energy-plant destruction for 10 days until April 6. Iran denying it requested the pause. Houthis warning they will enter the war. Lavrov saying the quiet part: “Iran did not violate any of its international obligations.” Russia’s oil revenue doubling to $24 billion this month.

Oil prices continued to spike this morning, with international Brent crude oil once again surpassing $110 per barrel. For the day so far that’s up another 3%. 

“After several glimmers of hope, fueled by comments from President Trump, which were quickly dashed, the market is becoming more demanding in terms of rhetoric,” said Amélie Derambure, senior multi-asset portfolio manager at Amundi. “The TACO trade is more difficult to do because a return to square one is not possible from here.”

Gulf Flashpoint Widens: Iran Signals No Let Up

Multiple GCC countries issued incoming-attack alerts as drones and missiles light up the region Friday, with Kuwait taking at least two new hits: Shuwaikh Port was struck by “hostile drones” – per the Kuwait Ports Authority, with a second target, Mubarak Al-Kabeer Port, reportedly hit by drones and cruise missiles. Infrastructure damage has been reported in both cases, but no reported casualties.

Saudi Arabia maintains its air defense footing, with the Ministry of Defense saying drones were intercepted and destroyed over Riyadh and the Eastern Province, following a warning for Al-Kharj – home to Prince Sultan Air Base. Six ballistic missiles were detected: two intercepted, with four splashing into the Persian Gulf and empty areas.

Absolute chaos in Tel Aviv…

Caos absoluto en Tel Aviv. La ciudad está en llamas. La sociedad israelí está viviendo su peor momento en décadas. Las nuevas oleadas de misiles de Irán son cada vez mas violentas y la situación se está volviendo insostenible. Se ha prohibido incluso la divulgación de todos los… pic.twitter.com/C5SDgtBigk

New explosions have been reported in Dubai and Abu Dhabi on Friday. It’s as if Iran and the IRGC are sending a clear “f-you” message to Trump in the wake of the series of ultimatums and deadlines Tehran never asked for. Trump earlier went from 48 hours to 5 days to now a 10-day window amid the threats to attack power and energy infrastructure.

Israel Escalates Too: Will ‘Intensify & Expand’ Strikes on Iran

The White House has been busy talking about its backchannel diplomacy and getting the beginnings of a peace deal off the ground via Pakistan, and at one point within the past week there was talk of Vice President J.D. Vance actually traveling to Islamabad – but the situation on the ground suggests the opposite, given also Israel has on Friday announced escalation of its posture. Israel has continued coming under consistent missile strikes.

Now, Defense Minister Israel Katz is vowing Israel’s attacks will “intensify and expand” – citing that Islamic Republic had not heeded warnings “to stop firing missiles at Israel’s civilian population.” Katz said: “The fire has continued – and therefore, IDF strikes in Iran will intensify and expand to additional targets and domains that assist the regime in developing and deploying weapons against Israeli civilians.”

There remains a huge risk for Israel amid the expectation that Iran has been saving its biggest and most advanced, longer range missiles – rationing its arsenal as it settles in for a long war.

Strait of Hormuz Status & Overnight News

Tehran could still be playing a double game of public rejection coupled with private behind-the-scenes signaling. According to Axios’ latest, Iranian officials are quietly showing interest in talks even as they reject Washington’s proposal, with mediators leaning hard to force  or ‘will into existence’ a meeting in the coming days. “Things are progressing very slowly” in terms of negotiations between the US and Iran, and as of now, no meeting between senior officials is even on the calendar, per Isreal’s i24NEWS.

The IRGC Navy is still declaring the Strait of Hormuz effectively shut: traffic “to and from” ports tied to enemy allies is banned outright, with warnings any movement will be “severely dealt with.” In a rare twist, The Wall Street Journal and others report Iran has even blocked two Chinese vessels from transiting Hormuz – signaling enforcement isn’t just for Western targets. Washington seems to be trying to adapt in real time, as Reuters reports the US has deployed uncrewed drone boats into the theater, opening yet another front in an already widening conflict.
