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 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. They flew on average 1,000 km (620 miles) and reached an altitude of 260 km (160 miles).

Some landed as close as 300 km (190 miles) from Japan’s northwest coast, Japan’s Defence Minister Tomomi Inada said in Tokyo.

The United States and Japan have requested a United Nations Security Council meeting on the launches, which will likely be scheduled for Wednesday, diplomats said.

The U.S. military on Monday left open the possibility of additional launch attempts.
