The Pentagon said Sunday a U.S. warship and multiple commercial vessels are under attack in the Red Sea. 

The development potentially marks a major escalation in a series of maritime attacks in the Middle East 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, according to the Associated Press. 

The Carney is an Arleigh Burke-class destroyer.
