North Korea has attempted to launch a missile on its east coast which is believed to have failed, South Korea's military says, APA reports quoting BBC.
It comes a day after the state warned the US that it was "ready to hit back with nuclear attacks" amid mounting tension in the region.
North Korea has already conducted five nuclear tests and a series of missile launches.
It is not yet clear what type of missile was tested on Sunday.
"North Korea attempted to test an unidentified type of missile from [its eastern port of] Sinpo," the ministry said, adding that the suspected launch on Sunday had "failed".
The ministry said that it was investigating for further details.
The US Pacific Command later confirmed the failed test.
"The missile blew up almost immediately," said US Navy Commander Dave Benham, quoted by Reuters news agency.
