South Korea retaliates after North Korea fires missile launches | USA TODAY

The U.S. Indo Pacific Command said the launches highlighted the “destabilizing impact” of North Korea’s illicit nuclear weapons and ballistic missile programs. The Japanese Defense Ministry said it also detected the launches and that the type of missiles used and their flight information were still being analyzed.

South Korea's Foreign Ministry said its top nuclear envoy held separate phone talks with his U.S. and Japanese counterparts soon after the launches. It said the three agreed to strengthen trilateral coordination on North Korea while repeating their calls for the North to stop weapons tests and return to talks.

Since late September, North Korea has launched a barrage of missiles toward the sea in what it called simulated tests of tactical nuclear weapons systems designed to attack South Korean and U.S. targets. North Korea says its testing activities were meant to issue a warning amid a series of South Korea-U.S. military drills. But some experts say Pyongyang has also used its rivals’ drills as a chance to test new weapons systems, boost its nuclear capability and increase its leverage in future dealings with Washington and Seoul.
