North Korea on Thursday fired a missile, presumed to be an intermediate-range ballistic Musudan, but the launch appeared to have failed, according to a South Korean military official.

The launch was made at around 6:50 a.m. from an area near the city of Wonsan, on North Korea's east coast, but the missile appeared to have crashed within a few seconds of being fired, the official said.

On April 15, North Korea fired another missile, also presumed to be a Musudan, from its east coast, but this too appeared to have failed, having also disappeared seconds after being launched.
