British Authority: Container ship hit by an unidentified projectile in Hormuz

It added that the incident is under investigation, advising vessels to "transit with caution and report any suspicious activity to the UK Maritime Trade Operations center."

In a second warning, the authority said it had received "a report from a credible source indicating that an oil tanker was hit by an unidentified projectile while departing the Strait of Hormuz."

The two warnings did not specify the name or nationality of the tanker and the container ship, the extent of the damage sustained, or the party that fired the projectiles at them.

The two incidents come amid tensions between Iran and the United States regarding navigation in the Strait of Hormuz, which is considered a strategic corridor for energy and commodity supplies and one of the most prominent negotiation files between Tehran and Washington.

Since April 2026, Iran has imposed restrictions on maritime traffic in the Strait, including designating alternative transit routes and requiring prior coordination with the Islamic Revolutionary Guard Corps (IRGC) naval forces.

On May 30, Iran announced that vessels transiting the Strait are required to obtain prior permission from the IRGC Navy, warning that transit without authorization constitutes a "security threat."

Military escalation began with a war launched by the United States and Israel against Iran on February 28, followed by a ceasefire in April, before confrontations between Washington and Tehran renewed amid stalled negotiations, despite the two parties signing a memorandum of understanding in mid-June.
