YEONPYEONG, SOUTH KOREA—North Korea defiantly test-fired another short-range missile Friday. This is the sixth missile fired by the communist country this week.
The rogue nation warned it would take "self-defense" action if provoked by the U.N. security council.
The council is considering tough sanctions against the communist regime for conducting a nuclear test.
On Monday the north conducted an underground nuclear test and then abandoned the truce that has kept peace between the Koreas since the Korean war ended in 1953.
The North's military says there is "a limit" to its patience, saying the five permanent members on the Security Council have "conducted 99.99 percent of the total nuclear tests" on Earth.
Chinese fishing ships are leaving the waters near the North-South border amid the possibility of naval skirmishes.
The U.S. is trying to calm fears, saying the situation isn't a crisis and no additional U.S. troops will be sent to the region.
