The North Korean GPS threatened passengers to Incheon International Airport in South Korea, one of the major airports. "According to the government, 667 aircraft were affected by North Korean GPS jamming signals since April 28. They include 618 Korean passenger planes, 48 foreign passenger planes, including 17 U.S., 10 Japanese and six Chinese, and one U.S. military aircraft." The jamming caused serious issues such as almost leading them into the North Korean territory. Because of this issue, South Korean sent a letter to North Korea via the boarder of the truce line, Panmunjom, but they refused to take any action against it. South Korea is seeking for international connections to protest against the North Korean GPS issue.
