Conflict Expansion

The Iran‑related war widened over the weekend to both the Red Sea and the Caspian Sea, even as the United States halted its airstrikes after thirteen consecutive nights of attacks, according to Reuters.

United States Military Posture

The U.S. military confirmed that its naval blockade of Iran remains fully operational, though it did not explain the pause in aerial operations. A senior Trump administration official indicated that diplomacy remains the President’s preferred route, while President Donald Trump reportedly stepped back from plans to intensify the campaign due to concerns about widening the conflict, depleting U.S. defence stockpiles, alienating Gulf allies, and disrupting global energy supplies.

Iranian Activity in the Gulf

Iran refrained from attacking neighbouring countries on Saturday, creating a temporary lull in Gulf‑region fighting.

Houthi Attacks on Saudi Energy Infrastructure

Iran‑aligned Houthi forces attacked Saudi Aramco facilities in the southern port city of Jizan and in Yanbu. Video footage showed smoke rising near the Jizan refinery, which can process up to 400,000 barrels of crude per day. Two missiles aimed at Yanbu were intercepted by a U.S.–made Patriot air‑defence system operated by Greek forces. Yanbu serves as a key export route for Saudi oil, allowing shipments to bypass the Iranian‑controlled Strait of Hormuz; a sustained Houthi campaign could threaten this secondary energy and commercial shipping corridor.

Yemeni Counter‑Operations

Saudi‑backed Yemeni forces responded by striking Houthi launch sites and weapons depots in the provinces of Marib and al‑Jawf. Both sides were reported to be mobilising troops, raising concerns that Yemen’s civil war could resume after the ceasefire that has been in place since 2022. The Houthis have also declared a naval blockade of Saudi Arabia and previously attacked two Saudi tankers in the Red Sea.

New Front in the Caspian Sea

In the Caspian region, Iran accused Ukraine of attacking an Iranian commercial vessel. An explosion on the vessel resulted in one sailor’s death and injuries to another crew member.

Ongoing Diplomatic Engagements

Washington and Tehran continue talks, though President Trump stated that Iran is not yet ready to reach an agreement. The U.S. blockade and threats against Red Sea energy infrastructure keep global oil supplies exposed despite the temporary pause in direct attacks.

Market Reaction

Oil price indicators reflected heightened tension: Light Crude Oil (LCO) rose 3.88%, Brent spot price increased 1.90%, and related market indices showed modest gains.

Summary of Key Points

  • Conflict has spread to two new maritime theatres while US air operations are on hold.

  • Houthi strikes targeted high‑capacity Saudi Aramco facilities; Greek‑operated Patriot system intercepted missiles.
