Iran Keeps Strait of Hormuz Closed and Riyadh Refinery Ablaze as Middle East Conflict Intensifies
Iran’s top negotiator said on Sunday that the Strait of Hormuz will remain closed until Washington meets seven conditions based on the Islamabad Memorandum. The announcement comes as talks aimed at ending the seven-month U.S.-Israeli war on Iran remain at an impasse, with Iran’s rial plunging to a record low near 2.7 million per dollar on the free market, according to Investing.com.
Strait of Hormuz Blockade Enforces Seven Conditions
Iran’s leadership insists that maritime transit through the critical passage will stay restricted until the United States changes its diplomatic approach. Parliament Speaker Mohammad Bagher Ghalibaf stated that the era of unilateral demands has concluded, noting that Washington has transmitted proposals via a mediator, as reported by Investing.com.
Meanwhile, Britain’s UKMTO shipping monitor reported that an unknown projectile struck the engine room of a tanker inside the strait. The vessel’s crew remained safe with no reported environmental impact, and no faction claimed responsibility for the strike. U.S. Defense Secretary Pete Hegseth characterized the coalition blockade surrounding the waterway as ironclad.
Saudi Aramco Pipeline Cuts Off European Refineries
Saudi Aramco notified at least two European refining customers that it will suspend crude oil shipments for the upcoming month following recent drone attacks on its major infrastructure, kr.investing.com reported, citing Bloomberg. The 1,200-kilometer East-West Pipeline typically transports 4 million to 5 million barrels of oil daily to the Red Sea port of Yanbu, representing about 4% to 5% of global supply.
Satellite imagery and industry sources cited by Reuters indicate that three pump stations sustained damage during the September 11 drone strikes, expanding initial damage assessments. European OECD nations, which imported hundreds of thousands of barrels of oil per day from Saudi Arabia in June via Red Sea pipeline networks and Egypt’s Sidi Kerir terminal, now face a total supply cutoff for October.
OPEC+ agreed in principle during Sunday discussions to maintain its November output targets, according to Reuters sources. Core members produced 25 million barrels per day in August, roughly 5 million barrels below prewar levels, as Gulf producers pump significantly below quotas due to export disruptions running 60-80% below normal.
Yemeni Clashes Spark Retaliatory Strikes on Riyadh
Yemen’s Houthis claimed responsibility for ballistic missile and drone strikes targeting a major facility near Riyadh, according to yahoo.com. Houthi military spokesman Yahya Saree stated that the operation retaliated against approximately 60 Saudi air strikes conducted over a 24-hour period, which included bombings in Sanaa.

The Saudi-led coalition dismissed the Houthi claims regarding Riyadh as misleading. Concurrently, coalition armed forces launched 97 targeted operations using warplanes, drones, and artillery against Houthi reinforcements along the Tor al-Baha front and Taiz axis. Yemeni government forces spokesman Colonel Majed Abdullah al-Nazili reported that the counter-operations neutralized at least 260 Houthi fighters and disabled 44 military vehicles.
Central Bank Currency Interventions and Mediation Efforts
To combat the collapsing value of the national currency, state television announced that Iran’s central bank has begun selling up to $2 billion to support the rial on the free market, as reported by Investing.com. Amid the diplomatic stalemate, Russian official Dmitry Medvedev stated that Moscow stands prepared to mediate the conflict.
