Liveblog: Iran War – Iran Closes Strait of Hormuz Again, Tanker Reportedly Attacked
On Saturday, April 18, 2026, Iran announced the closure of the Strait of Hormuz to international shipping, reversing a brief opening just days earlier, according to verified reports from maritime authorities. The development follows reports of an attack on a commercial tanker in the strategic waterway, prompting renewed tensions in the region.
The Iranian Foreign Minister Abbas Araghtschi had previously announced on April 11, 2026, that the Strait would remain open for commercial vessels as long as a U.S.-Iran ceasefire held, but recent hostilities have led to a reversal of that position. The closure was confirmed by maritime security agencies monitoring the area.
According to the United Kingdom Maritime Trade Operations (UKMTO), a commercial tanker came under fire from Iranian Revolutionary Guard Navy gunboats approximately 37 nautical miles northeast of Oman on April 18, 2026. The vessel’s captain reported the attack without prior warning, though the ship and crew were reported to be safe after diverting from the incident.
The attack on the tanker occurred amid broader regional instability, including a separate incident in southern Lebanon where a French UN peacekeeper was killed in an attack on a Blauhelm (UNIFIL) position. French President Emmanuel Macron confirmed the death of the French soldier and attributed responsibility to Hezbollah, calling for swift action by Lebanese authorities.
U.S. President Donald Trump has responded to the escalating situation by threatening to terminate the current two-week ceasefire agreement between the United States and Iran, which was brokered by Pakistan to allow for negotiations on ending the broader conflict. The ceasefire had previously facilitated the temporary opening of the Strait of Hormuz for commercial traffic.
Maritime analysts note that the Strait of Hormuz remains a critical chokepoint for global energy supplies, with approximately 20-30% of the world’s oil passing through the waterway. Any disruption to shipping has immediate implications for global energy markets and international trade.
International leaders have expressed concern over the deteriorating situation. Spanish Prime Minister Pedro Sánchez criticized the cycle of violence, stating he would not “applaud those who set the world on fire and then show up with a bucket,” reflecting broader unease among European leaders about the conflict’s trajectory.
The United Kingdom’s Prime Minister Keir Starmer had previously welcomed the initial ceasefire as a necessary pause for global stability, urging international partners to uphold the agreement and work toward a lasting resolution to secure the Strait and address underlying conflicts.
As of the latest reports, the situation remains fluid, with military and diplomatic channels active in attempts to de-escalate tensions. The international community continues to monitor developments in the Strait of Hormuz and surrounding regions for any further escalation or potential diplomatic breakthroughs.
The next key development to watch is the outcome of ongoing negotiations between U.S. And Iranian officials, which are expected to determine whether the ceasefire will be extended or terminated, directly influencing the status of the Strait of Hormuz for international shipping.
