North Korea has conducted GPS jamming attacks affecting ships and dozens of civilian aircraft in South Korea, the military reported. This incident follows North Korea’s recent test of an advanced solid-fuel intercontinental ballistic missile (ICBM). In response, South Korea launched its own ballistic missile as a show of strength. The South Korean military has issued warnings to vessels and aircraft operating in the Yellow Sea and urged North Korea to cease its provocative actions, threatening accountability for any ensuing consequences.
