North Korea fires ballistic missiles; US says no immediate threat

North Korea launched multiple ballistic missiles into the Sea of Japan, with one reportedly traveling over 900 km. This action is assessed by South Korean military and other sources as a direct response to South Korea's recent hypersonic missile test, continuing a pattern of tit-for-tat escalation on the Korean Peninsula. The specific missile types and full flight details remain unconfirmed, but the launches signal North Korea's ongoing military modernization and intent to maintain a hard line against Seoul.
