The jamming is believed to have prevented some US and South Korean bombs from hitting their targets during a military drill
SEOUL, March 8 (UPI) -- Seoul has accused North Korea of using sophisticated jamming systems to block South Korean military signals and disrupt its guided missiles.
South Korea's Yonhap news agency said the strong jamming signals have been transmitting from the northern border city of Keasong since last week.
The purported purpose of the jamming was to disrupt navigational devices using Global Positioning Systems as a major joint military exercise is under way northwest of Seoul.
The jamming is believed to have prevented some U.S and South Korean bombs from hitting their targets during a military drill. The Korea Communications Commission said they caused minor inconvenience last week.
