N. Korea Fires Short-Range 'Projectile' into Sea

North Korea fired a short-range projectile towards the sea off its east coast Monday in the latest of a series of missile and rocket tests, military officials said.

The projectile was launched at 10:30 am (01:30 GMT) at a site northeast of Pyongyang towards the Sea of Japan (East Sea), a spokesman for the South's joint chiefs of staff said.

"The projectile flew about 220 kilometers (1:30 miles), but we have no information yet on its type," he told Agence France Presse.

Monday's exercise came as cross-border military tensions run high following a series of missile, rocket and artillery launches in July and August.

Three weeks ago the North fired five short-range rockets into the sea just as Pope Francis arrived in Seoul for a five-day visit.

The North often fires missiles and rockets as a show of force or to express anger at perceived provocations, but the frequency of the recent tests is unusual.

U.N. resolutions bar North Korea from conducting any launches using ballistic missile technology.

But the North has defended the missile launches as a legitimate exercise in self-defense and a response to U.S. war maneuvers.
