North Korea warns U.S. could face 'unimaginable' strike

Yonhap is a South Korean press agency - report from them today on NK threats:

• Korean Central News Agency says Pyongyang could stage an "unimaginable" strike on the United States
• came as the South Korean and U.S. navies are staging joint drills in waters off the Korean Peninsula
• "The U.S. is running amok by introducing under our nose the targets we have set as primary ones. The U.S. should expect that it would face unimaginable strike at an unimaginable time"

Quite a lot of bluster about. Panties in wad all over the place.
