Korea tests missiles, slams US-S Korea drill

North Korea yesterday threatened to carry out more weapons tests after it fired its fourth pair of projectiles in less than two weeks following the start of joint exercises between the US and the South. The rising temperature on the peninsula threatens to derail putative negotiations between Pyongyang and Washington, with the North saying the combined drills were a "flagrant violation" of the process. Pyongyang has always been infuriated by military exercises between the South and US, seeing them as rehearsals for invasion, but in the past it has tended to avoid carrying out missile tests while the war games were taking place. The speed of its statement Tuesday was also unusual, coming within an hour of the launch, rather than the more normal day later.
