MANAMA, Bahrain >> The U.S. Navy says one of its guided-missile destroyers collided with an oil tanker early Sunday but that no one was injured in the accident.

The collision involving the USS Porter and the Panamanian-flagged bulk oil tanker M/V Otowasan occurred at approximately 1 a.m. local time, the U.S. Navy said in a statement.

The damage to the Porter is being evaluated and the incident is under investigation, the Navy added.

The USS Porter is on a scheduled deployment to the U.S. 5th Fleet, which is based in Bahrain.

The Strait of Hormuz, located at the mouth of the Persian Gulf, is where one-fifth of the world’s oil is routed. Tensions have risen there over Iran’s threats to block tanker traffic in retaliation for tighter sanctions by the West.
