North Korea to launch first military spy satellite in June, Japan on alert.

North Korea is set to launch its first military reconnaissance satellite in June, which it claims is for monitoring US activities. The move has drawn criticism over its potential use of banned missile technology. The launch would be the North's latest in a series of missile launches and weapons tests, including one of a new, solid-fuel intercontinental ballistic missile last month. Japan and South Korea have condemned the move, calling it a violation of UN sanctions, while the US State Department has warned that any North Korean launch using ballistic missile technology would violate UN resolutions.
