Sept. 13 (UPI) — One person died and four others sustained injuries Sunday after a commercial vessel was attacked in the Strait of Hormuz, Iranian state-run media reported.

Hossein Amir Teymoori, the governor of Qeshm, said the container vessel was struck by an “unidentified projectile,” IRNA reported. He said the ship was near Hengam Island when the attack happened early Sunday.

The United Kingdom Maritime Trade Operations Centre confirmed the attack, which happened late Saturday, British time.

“A vessel has been struck by an unknown projectile while transiting the Strait of Hormuz,” the UKMTO said in a post on X.

“Status of crew, damage assessment and environmental impact are unknown at present.”

In an update, the UKMTO said, “A fire has broken out onboard the vessel following the reported attack. Local authorities are on the scene and assisting in evacuating crew members.”

The United States has not claimed responsibility for the attack, The Hill reported. U.S. Central Command has yet to issue a response.

Iran and the United States have yet to reach an agreement to end the war in Iran and reopen the strait, which is a key transport lane for about 20% of the world’s oil.

Ebrahim Azizi, head of the Iranian parliament’s national security committee, said there are “no negotiations” in a post on X.

“Until Iran’s terms are met, talks are futile,” he wrote.
