North Korea denied on Friday that it played any part in a two and a half week long jamming of Global Positioning System (GPS) signals in the border area between North and South Korea.

The denial was carried in several state media outlets and said allegations that the DPRK was behind the jamming were part of “a new farce and smear campaign.”

The jamming took place between April 28 and May 14 and resulted in several hundred civilian aircraft and ships experiencing disruption to their navigation systems, according to reports. It made GPS signals unavailable or unreliable but didn’t result in any serious accidents. South Korean More >
