N. Korea Test Fire Short-Range Missiles

North Korea today test fired four short-range missiles having an estimated range of 200 kilometres, according to AFP. It was unclear what type of missiles were fired.

"Our military will maintain tight vigilance in preparation for additional launches or any military provocation from the North," a ministry official was quoted as saying.

North Korea carries out short-range missile tests on a fairly routine basis, and has used them before to display its anger at the annual military exercises.

The tests are unlikely to trigger a significant rise in military tensions. The South Korea-US drills kicked off Monday, despite vocal opposition from Pyongyang which views them as rehearsals for invasion.
