North Korea attempted to launch a missile from the eastern coastal city of Wonsan on Wednesday but appears to have failed, South Korea’s Ministry of National Defense (MND) has said.

“North Korea fired off one projectile of the missile nearby Wonsan airbase this morning (March 22, Wednesday), but it is presumed to have failed,” the MND said in a statement. “The United States and South Korea are aware of the issue, and [our] understanding is that the North’s missile wasn’t launched in a normal way.”
