A U.S. Navy strike group has been ordered to relocate to the western Pacific Ocean, providing a physical presence near the Korean Peninsula as concerns mount over North Korea's missile program.

The Pentagon announced the deployment late Saturday. In a statement, U.S. Pacific Command spokesman David Benham said the Carl Vinson Strike Group set sail toward the peninsula from Singapore.

Secretary of State Rex Tillerson says the U.S. doesn't want to take military action against North Korea, but "all of the options are on the table" if a serious threat arises. Tillerson made his frank remarks in a visit to South Korea on Friday, a day after saying diplomatic efforts "have failed" to persuade North Korea to abandon its nuclear program.

Tillerson's Asia tour began in Japan and will end in China. The top American diplomat is traveling without a press contingent.
