North Korea fired four ballistic missiles into the sea off Japan's northwest on Monday, angering South Korea and Japan, days after it promised retaliation over U.S.-South Korea military drills it sees as a preparation for war.
South Korea's military said the missiles were unlikely to have been intercontinental ballistic missiles (ICBM), which can reach the United States. The missiles flew on average 1,000 km (620 miles) and reached a height of 260 km (160 miles).
