North Korea says it has successfully launched a new type of long-range cruise missile.
Monday's edition of the ruling Workers' Party newspaper, Rodong Sinmun, says the Academy of Defence Science test-fired the new missiles on Saturday and Sunday.
The paper says the missiles hit targets 1,500 kilometers away after travelling for 7,580 seconds "along an oval and pattern-8 flight orbits" above the country's territorial land and waters.
Photos in the paper show a missile being fired from a mobile launch pad and during its flight.
It is believed that North Korean leader Kim Jong Un did not observe the test launches.
North Korea describes the long-range cruise missile as a "strategic weapon of great significance" in meeting the key target of the five-year plan for the development of the country's defense science and weapon system. It says the missile's development has been pushed forward for the past two years.
The US Indo-Pacific Command said in a statement that the reported missile launches highlight North Korea's continuing focus on developing its military program and the threats that poses to its neighbors and the international community.
South Korea's Joint Chiefs of Staff told reporters on Monday morning that an analysis is underway in close cooperation with the US intelligence authorities.
