An American warship and multiple commercial ships came under attack Sunday in the Red Sea, the Pentagon said, potentially marking a major escalation in a series of maritime attacks in the Mideast linked to the Israel-Hamas war.

“We’re aware of reports regarding attacks on the USS Carney and commercial vessels in the Red Sea and will provide information as it becomes available,” the Pentagon said.

The Carney is an Arleigh Burke-class destroyer.

The British military earlier said there had been a suspected drone attack and explosions in the Red Sea, without elaborating.
