(UDHAYAM, WASHINGTON) – North Korea has launched four ballistic missiles towards the Sea of Japan.
Three of them fell into Japan’s exclusive economic zone (EEZ) after flying some 1,000km (620 miles), in what PM Shinzo Abe called a “new stage of threat”.
They were fired from the Tongchang-ri region, near the North’s border with China, the South Korean military said.
The type of missile in unclear but the North is banned from any missile or nuclear tests by the UN.
The US military said later it had detected and tracked a launch but had determined that it did not pose a threat to North America.
On Friday, Pyongyang threatened to fire missiles in response to the Foal Eagle military exercises under way between South Korea and the US. The North sees the annual drills as preparation for an invasion against it.
Monday’s launches were just the latest in a long series of tests of North Korean missile technology, which experts say is likely to be improving with successive tests.
However, most believe the North is still some time away from being able to miniaturise nuclear warheads so they could fit on to a missile.
North Korea has repeatedly said its space programme is peaceful but it is believed to be developing an intercontinental ballistic missile that could strike the US.
Last month North Korea said it had successfully test-fired a new kind of ballistic missile in a launch supervised by leader Kim Jong-un.
It was the first test-firing since Donald Trump became the US president and was condemned by the UN, the US, South Korea and Japan.
Recent activity in the Tongchang-ri region, home to the Sohae Satellite Launching Station, has been a cause for concern for Japanese officials.
Screens have been set up in key areas at the site, probably to deter satellite surveillance, according to South Korea’s Yonhap news agency.
On Sunday, South Korea said it would quadruple the reward it pays defectors from the North who share information that will help enhance security to $860,000 (£700,000).
