North Korea fired multiple cruise missiles off its east coast on Wednesday, South Korea's military said.
The missiles were launched about 9 a.m. Wednesday (0000 Tuesday GMT) off the eastern coastal city of Wonsan, the Joint Chiefs of Staff (JCS) said.
"While strengthening surveillance and vigilance, our military is cooperating closely with the United States and closely monitoring additional signs and activities from North Korea," the JCS said in a statement.
