North Korea fired several cruise missiles off the west coast Friday, the South Korean military said, in the latest in a series of the North's cruise missile launches this year. The Joint Chiefs of Staff (JCS) said it detected the North's launch at around 11 a.m. from its west coast. It did not specify the number of missiles. "While strengthening our monitoring and vigilance, our military has been closely coordinating with the United States to monitor additional signs of North Korea's provocations," the JCS said in a text message sent to reporters. It marked the North's fourth cruise missile launch this year. Source: Yonhap News Agency
