TOKYO, Jan. 9 (Xinhua) -- Neither a Japanese tanker or a U.S. nuclear-powered submarine developed an oil or radiation leak after a collision in the Persian Gulf early Tuesday (Japan Time), Kyodo News reported.

   The 299,999-ton tanker Mogamigawa operated by Kawasaki Kisen Kaisha Ltd. collided with the 6,300-ton attack submarine Newport News under the command of the U.S. Navy's 5th Fleet headquartered in Bahrain at around 4:15 a.m. near the Strait of Hormuz, Japanese foreign ministry sources were quoted as saying.

    The Japanese Foreign Ministry received the report early in the morning.

    Nobody was injured in the collision but the sub's bow and the tanker's stern may have collided, Kyodo said.
