US-Israel-Iran War Latest Live News: A fresh security alert from the Strait of Hormuz has put commercial shipping on edge after a vessel was hit by an unknown projectile while passing through the strategically important waterway late on September 12. The United Kingdom Maritime Trade Operations (UKMTO) reported the incident early Sunday, but authorities have yet to establish what struck the vessel, who was behind the incident or how serious the damage may be.
The incident happened at around 23:00 UTC on September 12, according to the UKMTO advisory. The agency said the vessel was transiting the Strait of Hormuz when it came under attack. As of the September 13 warning, officials had not confirmed the condition of the crew, the extent of the damage or whether the incident caused any environmental impact.
The latest strike adds another layer of uncertainty for ships using the narrow waterway, which has remained at the centre of the wider US-Iran conflict and the disruption to regional energy and commercial traffic. Recent attacks and threats against merchant vessels have already sharply reduced shipping activity through the strait.

According to the latest UKMTO warning, the commercial vessel was sailing through the Strait of Hormuz when an unidentified projectile struck it.
UKMTO did not immediately identify the vessel, its flag, its operator or the type of projectile involved. The agency also did not assign responsibility for the attack.

The lack of information means the full circumstances remain unclear. Maritime authorities have started an investigation to determine what happened and assess the consequences for the vessel and its crew.
The incident was reported at approximately 23:00 UTC on September 12, with UKMTO issuing its warning on September 13.
US-Israel-Iran War Latest Live News: Crew Status and Damage Remain Unknown
The immediate priority remains determining whether anyone on board was injured and whether the vessel suffered significant structural or mechanical damage.
UKMTO said the crew’s status, damage assessment and environmental impact were unknown at the time of its advisory.
That means there was no confirmed information in the initial warning about casualties, flooding, fire, loss of propulsion or an oil spill.
Authorities are expected to gather more information as the investigation continues.

UKMTO urged vessels operating in the area to maintain heightened caution following the incident.
The agency also asked mariners to report suspicious activity while security forces and other authorities investigate.
The warning is significant because commercial ships have faced repeated security incidents around the Strait of Hormuz in recent months. Several vessels have been hit by projectiles, while others have faced disabling fire or other attacks during the escalating regional conflict.
In one recent August incident, UKMTO reported that a vessel was struck by an unknown projectile while travelling through the strait. That incident caused engine-room damage and a crew casualty, according to Reuters and UKMTO.
US-Israel-Iran War Latest Live News: Why the Strait of Hormuz Matters
The Strait of Hormuz is one of the world’s most important maritime chokepoints, linking the Persian Gulf with the Gulf of Oman and the wider Arabian Sea.
Any attack on commercial shipping through the route can have consequences far beyond the immediate incident. The waterway is vital to the movement of oil and other energy products from Gulf producers to international markets.
Shipping through the strait has already been severely disrupted during the US-Iran conflict. Recent reporting has pointed to vessel crossings falling dramatically from normal levels as operators face security risks and higher costs.
US-Israel-Iran War Latest Live News: Fresh Strike Comes Amid Wider Shipping Crisis
The latest vessel incident comes as tensions are rising across several key Middle Eastern shipping routes.
Saudi Arabia temporarily shut its major East-West oil pipeline after drone attacks, while Iran-backed Houthi forces have increased pressure around the Red Sea and Bab el-Mandeb. The developments have raised concerns about the security of alternative routes that energy companies rely on when Hormuz becomes difficult to navigate.
The United States has also adjusted how it provides air-defence coverage for commercial tankers travelling through the Strait of Hormuz, according to the Financial Times, highlighting the growing difficulty of protecting merchant vessels operating in the area.
US-Israel-Iran War Latest Live News: Who Attacked the Vessel?
There was no immediate claim of responsibility for the latest strike.
UKMTO described the weapon only as an “unknown projectile”, meaning the available information does not establish whether it was a missile, drone, rocket or another type of weapon.
Authorities will need to examine the vessel, collect crew accounts and assess other available evidence before determining what caused the strike.
For now, the incident remains under investigation.

The immediate focus will be on confirming the condition of the vessel and its crew, assessing any structural damage and determining whether the strike caused pollution.
Maritime authorities are also expected to examine whether the incident forms part of a broader pattern of attacks against commercial vessels in the region.
For ships still operating in or around the Strait of Hormuz, UKMTO’s latest warning reinforces the continuing security risks facing commercial traffic through one of the world’s most strategically important waterways.
