The US is moving four Navy ships off the coast of North Korea after reports that the North Korean government will launch a ballistic missile sometime between December 10 and 22.

 

The US is also warning North Korea to cancel the launch—the country's second this year following a failed launch in April.

"It should seem logical that we'll move them around so we have the best situational awareness," Adm. Samuel Locklear, who commands US forces in the Asia-Pacific region, told a Pentagon news conference, Reuters reported. "To the degree that those ships are capable of participating in ballistic missile defense, then we will position them to be able to do that."
