The United Arab Emirates has accused Iran of striking a tanker owned by the Abu Dhabi National Oil Company (ADNOC) with a missile as it crossed the Strait of Hormuz, drawing swift condemnation from Gulf and Arab governments.

The UAE Ministry of Foreign Affairs said on Saturday that the vessel was hit in the early hours of the morning while transiting the strategic waterway, a chokepoint for a large share of the world's seaborne oil.

Abu Dhabi described the strike as an act of piracy by Iran's Revolutionary Guard Corps (IRGC) and called on Tehran to halt the attacks and reopen the strait fully and unconditionally.

ADNOC confirmed one of its ships had been targeted by a missile while crossing the strait, according to the state news agency WAM. ADNOC did not provide details on any damage to the vessel or its exact location at the time of the attack.

The UAE ministry said using the waterway as a tool for pressure or economic blackmail threatened regional stability and global energy security.

The IRGC have previously threatened action against any vessels transiting the strait if they are linked to Tehran's adversaries, or if they fail to comply with Iranian directives.

ADNOC said on Friday that it had been significantly affected by what it described as unprovoked attacks on its personnel and assets, while continuing to meet customer requirements in an "exceptionally challenging environment."

The company said 15 of its vessels had been attacked by missiles and drones while transiting the strait since the start of the conflict, including three this week, killing one crew member and injuring 20 others. ADNOC did not identify those responsible for the attacks in its Friday statement.

Gulf Cooperation Council Secretary-General Jassim Mohammed al-Budaiwi condemned the latest attack as a "dangerous and unacceptable escalation", calling for international action to protect maritime navigation and reaffirming the bloc's solidarity with the UAE.

Qatar also condemned the attack and rejected the use of the Strait of Hormuz as a bargaining chip, calling for the waterway to be reopened without conditions. Doha's foreign ministry warned that its continued closure threatened the interests of regional states and the global economy.

Saudi Arabia condemned the targeting of the tanker "in the strongest terms," saying Iran's continued attacks constituted a grave breach of international law and Resolution 2817. Riyadh held Tehran responsible for the consequences and demanded an immediate halt to the strikes.

Jordan also condemned the attack as a flagrant violation of international law, affirming its full support for the UAE.

The reported attack marks a sharp escalation in tensions around the Strait of Hormuz, where the UAE and its Gulf neighbours have pressed for the passage to remain open to international shipping.
