North Korea has fired several short-range projectiles into the sea off its east coast from its eastern Kangwon province, South Korea’s military said.
The South Korean Office of the Joint Chiefs of Staff said the projectiles flew in a northeasterly direction for about 250km into the sea early on Saturday.
Earlier, South Korea’s Yonhap news agency said a ballistic missile may have been fired, without citing a source.
The launch is the first by the North since it test-fired a missile on July 28 that could have been designed to reach 10,000km, putting parts of the US mainland within reach.
The North’s move was immediately reported to South Korea President Moon Jae-in.
