The weaponry was moved to the peninsula’s east coast in the "last few days," a U.S. official confirmed.

The move comes after days of persistent threats from North Korean leader Kim Jong Un that identified the South, along with the U.S., as potential targets.

It is thought the missles are now Crisis in North Korea: Free Town Hall | Commonwealth Clubbeing hidden in an unidentified facility. Intelligence reports suggest the missiles are Musudans, which have a 2,500-mile range.

U.S. officials believe the missiles have been moved for a test strike and are waiting to see if the Pyongyang regime orders its airmen and seamen to stay clear of the area.

Defense Secretary Chuck Hagel said on Thursday that the U.S. is taking the provocative rhetoric from Pyongyang "very seriously." Many military analysts believe North Korea would never genuinely consider an attack on the U.S., but have also expressed alarm at the mental stability of the communist country’s leader.

Some believe that the increasingly belligerent talk is merely aimed at cementing the domestic authority of Kim Jong Un.

South Korea, gripped by jitters over Pyongyang’s accusation that the U.S. is sending the region to "the brink of war," has sent Aegis destroyers equipped with advanced radar systems to both of its coasts, CNN reports.

Confusion in the region was further fueled by Denis Samsonov, the press officer of the Russian embassy in Pyongyang, who announced this week that North Korea has asked the embassy to consider a possible evacuation of its staff because of the tensions in the region.

"The Russian side has taken note of this suggestion. No decision has been made yet," he said.

News of the loaded missiles caps off a month of increased activity in the region. Here is a timeline leading up to Friday’s announcement.
