Kyodo - U.S. intelligence has detected the departure from a North Korean port of a North Korean ship suspected of carrying military equipment banned under a U.N. sanctions resolution against Pyongyang's Oct. 9 nuclear test, CBS News reported Thursday.

The United States is tracking the ship, CBS said, noting that it remains uncertain exactly what the ship is carrying and where it is headed.

Should the ship be confirmed to be loaded with nuclear, missile or other related materials, it could be subject to the first maritime inspection under the sanctions resolution adopted unanimously Saturday by the U.N. Security Council. The resolution, which imposes economic and diplomatic sanctions, rules out military options, which are strongly opposed by China and Russia.

The news report came a day after U.S. President George W. Bush vowed to deal with ships and airplanes and take all necessary measures to stop North Korea's transfer of nuclear weapons to other nations and non-state entities such as terrorists.

Bush warned North Korean leader Kim Jong Il in an interview with ABC News that Kim will be ''held to account'' and face ''grave'' consequences if Pyongyang sells nuclear arms.

Under the resolution, U.N. members are required to conduct maritime inspections and take other measures, if necessary, to stop North Korea's transfer of nuclear, missile and other military equipment.
