SEOUL, South Korea --- South Korean officials said North Korea fired an unidentified projectile from its capital, Pyongyang, that flew over Japan. This is an especially aggressive test-flight that will rattle an already anxious region, said officials.

Seoul’s Joint Chiefs of Staff said the South Korean and U.S. militaries were analyzing the launch and did not immediately confirm how far the projectile traveled.

Japanese officials said the missile flew over the northern Japanese island of Hokkaido and landed in the Pacific Ocean. There was no damage to ships or anything else reported.

Japan’s NHK TV said the missile separated into three parts.
