Tokyo, January 04 (QNA) - North Korea launched at least two ballistic missiles eastward on Sunday that apparently fell outside Japan's exclusive economic zone, with no damage to ships or aircraft reported, according to the Japanese government.

The missiles were launched from North Korea's west coast, with both reaching a maximum altitude of around 50 kilometers and flying about 900 km and 950 km, respectively, Japan's Defense Ministry said.

Defense Minister Shinjiro Koizumi told reporters at his ministry that Tokyo has strongly protested to Pyongyang over the launch, saying the nation's actions, including previous missile launches, "threaten the peace and security" of Japan, the region and the international community, according to Japan News Agency (Kyodo).

The two projectiles may have flown on irregular trajectories, Koizumi said, adding that Japan will "closely collaborate" with the United States and South Korea in analyzing the details of the latest missile launches.

Japanese Prime Minister Sanae Takaichi instructed officials to gather information and swiftly provide necessary details to the public while ensuring the safety of vessels and planes and preparing for contingencies, her office said.

North Korea last fired a ballistic missile on Nov. 7, which Japan's Defense Ministry said was launched eastward from North Korea's west coast and flew over 450 km. (QNA)
