South Korea and the United States fired eight ballistic missiles into the East Sea, Monday, in response to North Korea's missile launches the previous day, according to the South's military.

The Joint Chiefs of Staff (JCS) said that the allies launched the ground-to-ground Army Tactical Missile System (ATACMS) missiles for around 10 minutes from 4:45 a.m.

On Sunday, the North fired eight short-range ballistic missiles (SRBMs) from four different locations into the East Sea following a South Korea-U.S. naval exercise last week involving an American aircraft carrier.

"The South Korea-U.S. combined firing of the ground-to-ground missiles demonstrated the capability and posture to launch immediate precision strikes on the origins of provocations and their command and support forces," the JCS said in a press release.
