North Korea has recently mixed its weapons tests with conditional talks with Seoul

North Korea says it has test-fired an anti-aircraft missile in the fourth round of weapons launch this month.

The Korean Central News Agency said Friday the test-launch performed on Thursday is “of very practical significance in studying and developing various prospective anti-aircraft missile system.”

North Korea has recently mixed its weapons tests with conditional talks with Seoul in what some experts say is an attempt to extract outside concessions.
