North Korea launched three ballistic missiles early Tuesday in Pyongyang's latest defiance of United Nations resolutions against the communist regime's use of such military technology, the South Korean news agency Yonhap reported, citing the South Korean military.
The rockets, believed to be modified from outdated Soviet SCUD missile systems with a range of up to 600 kilometres, were fired from northern North Korea toward the Sea of Japan.
The missiles were fired between 5:45 am and 6 am (2045-2100 GMT Monday), the report said
The launches were thought to be a riposte to the decision by the United States and South Korea to install an advanced missile system known as THAAD by the end of next year, Yonhap reported.
Pyongyang has fired several rockets in recent weeks.
The last previous launch was July 9, when a North Korea ballistic missile exploded shortly after being fired from a submarine.
