Saudi Arabia has condemned an Iranian attack on one of its oil tankers in the Strait of Hormuz that killed two Filipino crew members, Bahri confirmed.

The vessel, Sidr, was transiting the strait on August 31 when it was caught up in what Bahri described as a “security incident”. The kingdom’s foreign ministry announced its condemnation on September 2, according to Arab News.

The ministry also denounced separate Iranian drone and missile strikes on Jordan, Bahrain and Kuwait, and voiced “full support and solidarity” with the three states in defending their security and sovereignty. Arab News reported that Tehran had lashed out at Washington’s Arab allies this week following fresh US strikes on Iranian targets on August 30.

In its statement, Riyadh called for an end to hostilities and for “respect for the safety of international navigation and global energy supplies”, while urging adherence to the principles of “good neighbourliness and state sovereignty”.

“The Kingdom calls on all parties to calm down, stop escalation, respect international law and return to negotiations and peaceful solutions,” the ministry said.

The strike on the Sidr drew condemnation from across the Gulf. Kuwait’s foreign ministry called it a “heinous attack” and a “grave violation” of international law. Qatar described the incident as a flagrant breach of the freedom of maritime navigation. Jordan’s foreign ministry expressed “absolute solidarity” with Saudi Arabia.

Dozens of commercial vessels have been struck by Iranian forces in the Strait of Hormuz since war between Tehran and the United States erupted more than six months ago. Shortly after hostilities began, Iran moved to obstruct merchant traffic through the waterway, the single most important artery for seaborne crude and LNG cargoes leaving the Gulf.

The targeting of a Bahri-flagged vessel marks a sharp escalation for Saudi Arabia, which has until now largely avoided direct maritime confrontation with Iran during the current conflict. Bahri operates one of the world’s largest VLCC fleets and is the principal lifter of Saudi Aramco crude to international markets.

Neither Bahri nor the Saudi authorities have detailed the nature of the weapon used against the Sidr, the extent of damage to the hull or cargo, or the vessel’s current status. Iran has not publicly acknowledged responsibility for the incident.
