North Korea threatens to fire at South Korea

SEOUL, South Korea — North Korea's military threatened Sunday to fire at South Korea, as Seoul prepared to start annual joint drills with US troops, maneuvers Pyongyang says are a rehearsal for an invasion.
The North's military warned that it would fire at South Korean border towns if Seoul continued to allow activists to launch propaganda leaflets toward the communist country, Pyongyang's official Korean Central News Agency said. The warning was conveyed to South Korea's military earlier Sunday, it said.
"South Korea's traitor puppet regime must recognize the seriousness of the situation and immediately stop anti-(North Korea) psychological warfare," the KCNA said.
It accused South Korean activists and lawmakers of flying balloons carrying hundreds of thousands of leaflets critical of North Korea's government on the North's most important national holiday, an apparent reference to leader Kim Jong Il's 69th birthday, which fell on Feb. 16.
