SEOUL -- North Korea's leader Kim Jong Un has declared the end of the country's "evil relationship" with South Korea, official media on Friday quoted him as saying, as Pyongyang escalates both rhetoric and action toward its longtime rival for control of their divided peninsula.
Kim's comments came after Pyongyang on Tuesday blew up roads and railways connecting his country to the South, the latest step in a seeming effort to cut off all access to the South.
