North Korea has fired a new ballistic missile, according to South Korean media.
Yonhap, a South Korean news agency, quoted military officials saying that the missile flew towards the east from Pyongsong in Pyongan province.
The claims were then confirmed by a US government source.
The Pentagon said it was assessing the ‘probable’ launch, but confirmed that it happened at 3.30am local time (6.30pm GMT).
US authorities are now working with South Korea to analyse the missile’s trajectory, and to work out what range it had.
It’s not yet known how far it went or whether it flew over Japan, like other missiles launched earlier this year.
North Korea has already fired a number of test missiles throughout this year, causing tensions to rise with the international community.
These included the country’s first intercontinental ballistic missiles.
In August, Japanese citizens were woken up to J-Alerts on their mobile phones at 6.02am warning them that a missile was flying over the country.
The missile test was later condemned by Japanese PM Shinzo Abe as ‘reckless’.
