[Al Arabiya Latest] North Korea test-fired another short-range missile off its east coast on Friday and said it would take more "self-defense measures" if the United Nations Security Council punished it for this week's nuclear test.South Korea said an increasingly aggressive North may be preparing fresh moves after Chinese fishing boats were spotted leaving a disputed sea border on the west coast.
South Korea and the United States put their troops on the Korean peninsula on higher alert on Thursday, and Seoul's defense ministry said forces were keeping a close watch on the land and sea border with the North.
