MANAMA, Bahrain — One of the U.S. Navy's guided-missile destroyers suffered minor damage when it collided with an oil tanker early Sunday just outside the strategic Strait of Hormuz.

The collision left a gaping hole in the starboard side of USS Porter, but no one was injured on either vessel, the U.S. Navy said in a statement. The collision with the Panamanian-flagged bulk oil tanker M/V Otowasan occurred at approximately 1 a.m. local time.

The cause of the incident is under investigation, the Navy said, adding that there were no reports of spills or leakages from either the USS Porter or the Otowasan.
