The U.S. military is tracking a flagged North Korean ship suspected of proliferating weapons material in violation of a U.N. Security Council resolution passed last Friday, FOX News has learned.
The ship, Kang Nam, left a port in North Korea Wednesday and appears to be heading toward Singapore, according to a senior U.S. military source. The vessel, which the military has been tracking since its departure, could be carrying weaponry, missile parts or nuclear materials.

The apparent violation raises the question of how the United States and its allies will respond, particularly since the U.N. resolution does not have a lot of teeth to it.
