DUBAI, Aug. 12 (Xinhua) -- A U.S. Navy guided missile destroyer collided with a large Japanese-owned merchant oil tanker near the Strait of Hormuz on Sunday morning, causing no casualties, the U.S. Navy said on its website.
The collision between USS Porter and the Panamanian-flagged bulk oil tanker M/V Otowasan occurred at about 1 a.m. local time, the Navy said.
The destroyer was still able to operate under its own power, it said, adding "overall damage to Porter is being evaluated."
The incident was under investigation, and the collision was not combat related, the Navy said.
The U.S. vessel was on a scheduled deployment mission for maritime security operations.
