According to Reuters, a U.S. Navy strike group will be moving toward the western Pacific Ocean near the Korean peninsula, a U.S. official told Reuters on Saturday, as concerns grow about North Korea's advancing weapons program.  The strike group, called Carl Vinson, includes an aircraft carrier and will make its way from Singapore toward the Korean peninsula.

The move of the USS Carl Vinson "is in response to recent North Korean provocations", an official told CNN. "We feel the increased presence is necessary," the official said, citing North Korea's worrisome behavior." 

Harry Harris, the commander of U.S. Pacific Command, directed the USS Carl Vinson strike group to sail north to the Western Pacific after departing Singapore on Saturday, Pacific Command announced.
