DUBAI, United Arab Emirates (AP) _ A U.S. Navy destroyer collided with an oil tanker in the Persian Gulf off Iraq, slightly injuring four people, the Navy said Sunday.

The USS McCampbell collided with the tanker late Saturday about 30 miles southeast of the Iraqi coastline. Two sailors and two crew members of the tanker were treated for minor injuries at the scene, Navy spokeswoman Lt. Leslie Hullryde said.

No oil was spilled in the collision. Both ships suffered minor damage but were deemed seaworthy.

The oil tanker was flying the flag of the Pacific island nation of Kiribati.

McCampbell, home-ported in San Diego, is one of several coalition forces vessels conducting maritime security operations for southern Iraqi ports. Oil passing through the terminals is the main source of revenue for Iraqi reconstruction.

Saturday's collision was at least the third for a Navy vessel in the Gulf since 2004.

In August 2004, a small traditional Arab sailboat crashed into the USS John F. Kennedy. None of the sailboat's passengers were found.
