North Korea fired multiple cruise missiles toward the Yellow Sea, South Korea's Joint Chiefs of Staff said.
The South Korean military stressed that the country is analyzing the launches, which took place around 4 am local time, together with the United States in order to find out more details.
The tensions surrounding North Korea have risen recently after Pyongyang condemned the US nuclear submarine port call in South Korea and warned it could use nuclear weapons if it "determined that a nuclear attack on the country has been undertaken or is imminent"
