The DPRK launched three ballistic missiles on Tuesday morning, a week after the ROK announced where it intended to set up an advanced US missile defense system.

The latest missile launches show that the Republic of Korea's decision to deploy the Terminal High Altitude Area Defense system will undermine security on the Korean Peninsula, analysts said.

On July 13, Seoul announced it had decided with the United States to deploy the THAAD system in Seongju county, ROK, to counter threats from the DPRK.
