North Korea launched an "unidentified short-range missile" towards the East Sea -- also known as Sea of Japan -- on Saturday, Seoul's Joint Chiefs of Staff (JCS) said.
Pyongyang "fired a missile from its east coast town of Wonsan to the eastern direction at 9:06 am (0006 GMT) today," the JCS said in a statement.
South Korea and the United States "are analysing details related to the missile", it added.
It comes after South Korean foreign minister Kang Kyung-wha said Friday that Pyongyang needs to show "visible, concrete and substantial" denuclearisation action if it wants sanctions relief, as the North's deadlock with the United States continues.

Kang's comments at a press conference come just days after a senior North Korean official warned Washington of an "unwanted outcome" if it didn't adjust its stance on economic sanctions.
Washington and Pyongyang have been at loggerheads since the collapse of a summit between North Korean leader Kim Jong-un and US President Donald Trump in February.
The summit broke down after cash-strapped Pyongyang demanded immediate sanctions relief, but the two sides disagreed on what the North should give up in return.
