NoKor jams GPS signals, affecting ships, aircraft in South

North Korea staged GPS jamming attacks on Friday and Saturday, an operation that was affecting several ships and dozens of civilian aircraft in South Korea, Seoul's military said.

The jamming allegations come about a week after the North test-fired what it said was its most advanced solid-fuel ICBM missile.

The South fired its own ballistic missile into the sea on Friday in a show of force aimed at demonstrating its resolve to respond to "any North Korean provocations."
