Level 1 - Absolute Beginner

Iran attacked a ship near the Strait of Hormuz. The ship had a Singapore flag. Its name was Ever Lovely. An Iran drone hit the ship.

The ship's bridge was damaged. No one was hurt. The ship was leaving the Strait of Hormuz when it was attacked.

The US and Iran made a deal in June 2026. The deal said ships could pass through the strait safely. Iran's attack broke the rules of the deal.

The United Nations stopped a plan to move ships out of the Gulf. They want to make sure ships are safe first before the plan continues.

Level 2 - Elementary

On June 25, 2026, a drone from Iran's Revolutionary Guards hit a cargo ship called Ever Lovely in the Strait of Hormuz. The ship carried a Singapore flag. The drone struck the right side of the ship, called the starboard side, and damaged the bridge. No crew members were hurt and there was no environmental damage.

The ship was about 7.5 miles from the Omani port of Dahit when it was hit. The attack was a challenge to a recent agreement between the United States and Iran. The two countries signed a deal in June 2026 that said ships could pass through the strait for 60 days without paying tolls.

Iran has also insisted that ships must ask for its permission before passing through the strait and must sail close to the Iranian coast. The United States and other countries say ships have the right to sail freely under international law.

After the attack, the UN's International Maritime Organization paused its plan to help ships leave the Persian Gulf. The IMO Secretary-General said the pause was needed to make sure safety could still be guaranteed for ships in the area.

Level 3 - Intermediate

On June 25, 2026, a drone operated by Iran's Islamic Revolutionary Guard Corps struck the Ever Lovely, a Singapore-flagged cargo ship, as it was exiting the Strait of Hormuz. The drone struck the vessel on its starboard side approximately 7.5 nautical miles southeast of Oman's port of Dahit, damaging the ship's bridge. Although no casualties were reported and there was no environmental impact, the attack immediately drew international condemnation.

The incident represented a direct challenge to the memorandum of understanding signed between the US and Iran in June 2026 at Burgenstock, Switzerland. Under the MoU, Iran had committed to facilitating toll-free safe passage for commercial vessels through the strait for a period of 60 days. Despite this commitment, Iran has continued to assert its right to regulate shipping lanes and has not ruled out imposing transit fees once the MoU's term expires.

In response, the UN's International Maritime Organization temporarily suspended its coordinated plan to evacuate the dozens of commercial ships stranded in the Persian Gulf since the onset of the US-Iran naval conflict. Secretary-General Arsenio Dominguez stated that the pause was necessary 'in order to reconfirm that the necessary safety guarantees continue to be in place.'

The incident underscored the fragility of the June agreement and the complex dispute over navigation rights in the strait, through which approximately 20 percent of global oil trade passes. Iran insists that ships must use a route close to its coastline and seek its permission before transiting, while the US and its regional allies maintain that the right of innocent passage is guaranteed under international maritime law.

Level 4 - Advanced

A drone operated by Iran's Islamic Revolutionary Guard Corps struck the bridge of the Ever Lovely, a Singapore-flagged cargo vessel, approximately 7.5 nautical miles southeast of Oman's port of Dahit on June 25, 2026, as the ship sought to exit the Strait of Hormuz via the US-preferred Omani coastal route. The attack, which damaged the starboard superstructure without causing casualties or an environmental release, was the most provocative challenge yet to the memorandum of understanding reached at Burgenstock, Switzerland, under which Tehran had pledged to facilitate toll-free commercial passage through the strait for a 60-day period.

The incident forced the immediate suspension of the International Maritime Organization's coordinated evacuation programme for the dozens of vessels stranded in the Persian Gulf since the outbreak of the US-Iran naval confrontation. IMO Secretary-General Arsenio Dominguez announced the halt, stating that the process would restart only once it had been 'reconfirmed that the necessary safety guarantees continue to be in place.' The implicit admission that those guarantees were in doubt cut to the heart of the continuing dispute over sovereign jurisdiction of the strait.

At the core of the standoff lies a fundamental disagreement over the nature of transit rights in a waterway through which roughly one-fifth of globally traded oil flows. Iran maintains that commercial vessels must request Iranian authorisation before transiting and must use a route running closer to its coastline than to Oman's; the United States and its Gulf partners insist that the right of innocent passage, codified under the 1982 UN Convention on the Law of the Sea, is non-negotiable and that any Iranian attempt to levy tolls or impose routing constraints constitutes a violation of international maritime law.

The attack on the Ever Lovely demonstrated that Iran retains both the capability and the willingness to conduct kinetic operations against commercial shipping despite the diplomatic framework it signed weeks earlier. Brent crude spiked on news of the strike before retreating modestly, and Lloyd's war-risk underwriting rates for vessels transiting the strait were expected to rise sharply. Market participants remained alert to the possibility that the MoU could unravel entirely if further attacks followed - a prospect that would re-expose global energy markets to the disruption that had driven Brent above $109 at the peak of the US-Iran conflict.
