North Korea continues GPS jamming attacks against South Korea for the second day since Friday.

According to Seoul's Joint Chiefs of Staff(JCS) on Saturday, the GPS jamming provocations from the North's Haeju and Gaeseong regions have disrupted the operations of dozens of South Korean vessels and civilian aircraft.

The JCS urged vessels and planes operating near the Yellow Sea to beware of such attacks.

The South Korean military also called on Pyongyang to immediately cease its provocations, and warned that the regime will be held accountable for all related issues.

North Korea previously conducted GPS jamming near the de facto maritime border of Northern Limit Line(NLL) between May 29 and June 2 this year. The attacks resumed and were carried out intermittently since early October.
