Kim Yo Jong, sister of North Korean leader Kim Jong Un, warned that North Korea will launch an immediate military strike in response to any provocation. This comes after the North fired more than 60 artillery rounds near the disputed maritime border with South Korea. South Korea's Yonhap news agency reported that the North continued to fire shots on Sunday. Kim Yo Jong stated that the Korean People's Army is ready to strike if provoked, and South Korea's military has urged North Korea to cease military activity near the border.
