Two Tankers Struck Near Strait of Hormuz as Iran Sets Conditions for Reopening

The United Kingdom Maritime Trade Operations Centre (UKMTO) reported on Saturday that a crude oil tanker was hit by an unknown projectile four nautical miles east of Oman. A second tanker was struck on Sunday in the Strait of Hormuz, causing damage to its engine room. The attacks come as part of a series of strikes on shipping in the strait, through which about a fifth of global oil supplies transited before the outbreak of the U.S.-led war on February 28.

Iranian Parliament Speaker Mohammad Bagher Ghalibaf, quoted by state media agency Nour News, said on Sunday: "The Strait of Hormuz will not open until Iran's seven conditions based on the Islamabad Memorandum are met, and Iran will not regulate its national security with tweets from American officials." The Islamabad Memorandum of Understanding was an interim deal signed in June between President Donald Trump and Iranian President Masoud Pezeshkian, which led to a brief pause in hostilities. Tehran's conditions include a halt to U.S. "acts of aggression," an end to the naval blockade, cessation of economic warfare, and the release of Iranian assets. The U.S. has demanded that Iran dismantle its nuclear weapons program.

Separately, Yemen's Iran-aligned Houthis said they had targeted a Saudi Aramco facility in Riyadh with ballistic missiles and drones, according to Reuters, in retaliation for Saudi attacks on Yemen's Sanaa and other provinces.

Meanwhile, the United States is deploying the USS Theodore Roosevelt carrier strike group and 2,000 Marines to the Middle East as part of a wider military buildup around Iran, Al Jazeera reported.

Analysis

Why This Matters

The Strait of Hormuz is a critical chokepoint for global oil shipments; disruptions threaten energy markets and could raise fuel prices worldwide.
Continued attacks on tankers and infrastructure risk escalating into a broader regional conflict involving Iran, the U.S., Saudi Arabia, and Yemen's Houthis.
The deployment of additional U.S. Marines and a carrier strike group signals a heightened military posture that could further strain diplomatic efforts.

Background

Tensions have been high since the start of the U.S.-led war on February 28, 2026. A brief ceasefire was achieved in June with the Islamabad Memorandum of Understanding, but hostilities have resumed. Iran has used its control over the Strait of Hormuz as leverage, with recent weeks seeing regular attacks on commercial shipping. The U.S. has maintained a naval blockade and demands that Iran abandon its nuclear program.

Key Perspectives

Iran: Tehran insists the strait will remain effectively closed until its seven conditions are fulfilled, including an end to U.S. aggression and the release of frozen assets. It views the waterway as a bargaining chip to secure broader concessions. United States: Washington has called for the dismantling of Iran's nuclear weapons program and the free passage of ships. The deployment of additional forces indicates a willingness to use military means to secure the strait if diplomacy fails. Saudi Arabia and the Houthis: The Houthi attack on Saudi Aramco facilities underscores the wider regional dimension, linking the Yemen conflict to the Iran-U.S. standoff. Saudi Arabia is a key U.S. ally but has also sought to de-escalate.

What to Watch
