North Korea has launched a new ballistic missile, according to South Korean media.

The news was confirmed by a US government source.

The South Korean news agency Yonhap reported that the rocket flew east of Pyongsong in South Pyongan Province.

It is not clear how far it went or whether it flew over Japan like other rockets launched earlier this year.

US President Donald Trump was briefed while the rocket was still in the air, the White House said. He then visited Congress, but has since returned to the White House.

The South Korean military said it had responded to the launch with a missile exercise of its own.

The Prime Minister of Japan convened an emergency meeting of the Council of Ministers on the occasion of the new launch of a missile from North Korea, according to government spokesman Yoshihide Suga.

The rocket may have landed in Japan's exclusive economic zone, NHK television reported, citing Defense Ministry sources.

North Korea has tested several other missiles this year, including the first intercontinental ballistic missiles, as tensions rise over its nuclear program.

South Korean and U.S. authorities are working together to analyze the course of the latest missile, according to a statement from South Korean military leaders. It is not clear what the scope was.

Earlier on Tuesday, two sources in Washington said U.S. government officials said North Korea could launch a new missile test in days, the first missile launch since it took place in mid-September over Japan.

North Korea is considered to be focusing its efforts on building long-range missiles. Pyongyang officials said the first of the long-range missiles tested in July could hit "any part of the world," but the U.S. military described it as a mid-range missile.
