Pyongyang, North Korea (Web Desk): Nuclear-armed North Korea claimed that its missile launches were training for an attack on US bases in Japan , as global condemnation of the regime swelled.

The latest declaration from Pyongyang comes the day after it launched four ballistic missiles 600 miles into the Sea of Japan , in an alarming show of strength.

Three of the four missiles fired on Monday landed provocatively close to US ally Japan , in waters about 300 km to 350 km from Oga Peninsula in Akita prefecture that are part of its exclusive economic zone, representing a challenge to American President Donald Trump.

Trump and Japanese Prime Minister Shinzo Abe warned in a phone call that the threat from North Korea had “entered a new stage”.

Both United States and Japan requested United Nations Security Council (UNSC) to hold an emergency meeting over the escalating threat of North Korea .

Earlier on Tuesday, United States also started to deploy the first elements of its advanced anti-missile defense system in South Korea following the North Korea 's test launch.
