According to Reuters, the incident comes a day after an attack on a cargo ship, further escalating tensions in the region. Following these developments, the Joint Maritime Information Center, which monitors international shipping security, has raised the maritime threat level.
UKMTO said there was no report of environmental damage as a result of the attack. The organization is a British military body responsible for monitoring global sea routes and issuing maritime security alerts.
Earlier, Iran’s Islamic Revolutionary Guard Corps (IRGC) stated that, in response to US strikes on Iranian coastal areas, it had targeted US-linked assets in the region. The IRGC claimed that the United States used an alleged attack on a commercial vessel in the Strait of Hormuz as justification for airstrikes on Iran’s coastal areas.

On the other hand, US Central Command (CENTCOM) confirmed that American forces targeted missile and drone storage facilities and coastal radar sites in Iran on June 26. According to CENTCOM, the operation was a response to an Iranian attack on a commercial vessel passing through the Strait of Hormuz on June 25.
CENTCOM described Iranian actions against commercial shipping as “unprovoked aggression” and a clear violation of a ceasefire agreement. It added that US forces remain in the region and are closely monitoring the situation to ensure compliance with all provisions of the agreement with Iran.
Reuters reported that tensions between the US and Iran have once again escalated following the latest strikes, with both sides accusing each other of violating a provisional peace agreement reached in Switzerland.
The US said it carried out overnight strikes on Iranian targets, while Iran claimed it conducted retaliatory attacks on US-linked positions. Both sides maintain that the other has violated the ceasefire framework.
Iranian state television reported that the IRGC issued warning shots at vessels not using designated Iranian shipping lanes. It added that several ships subsequently began seeking Iranian permission to pass through the Strait of Hormuz, though Tehran did not formally confirm any specific attack on a commercial vessel.
Bahrain condemned an alleged Iranian drone strike over its territory, calling it a violation of the ceasefire agreement, while Iranian officials accused the US of failing to uphold its commitments, including those related to the Lebanon ceasefire.
Iranian MP Ibrahim Azizi strongly criticized the US response, saying Washington had once again attacked Iran during ongoing negotiations. He said the US president had shown disregard for both diplomatic principles and ceasefire obligations, warning that such violations would ultimately lead to “retreat and regret.”
Iran’s Foreign Ministry spokesperson Esmail Baghaei also called the US strikes a “clear violation” of understandings between Tehran and Washington, accusing the US of targeting Iranian coastal surveillance facilities.
The ministry urged regional countries along the Gulf not to allow their territory to be used for attacks against Iran.
US Vice President JD Vance, however, said Washington had fully adhered to the ceasefire agreement. He added that if Iran had concerns about implementation, it should engage directly through dialogue, warning that “violence will be met with violence.”
The US said its strikes followed an Iranian drone attack on a commercial vessel on June 25, targeting missile and drone storage sites and coastal radar installations in Iran.
