North Korea on Tuesday fired what appeared to be a ballistic missile into its eastern sea, its second weapons launch in a week, the militaries of South Korea and Japan said.

Iran PressAsia: North Korea fired what may be a ballistic missile on Tuesday, the Japanese coast guard said, the second apparent missile launch in less than a week after the reclusive state's leader urged the military to make more military advances.

South Korea's military also confirmed the launch of an "unidentified projectile," without elaborating.

Last week, North Korea said it fired a "hypersonic missile" that successfully hit a target on Wednesday.

The test launches by nuclear-armed North Korea underscored leader Kim Jong Un's New Year's vow to bolster the military to counter an unstable international situation amid stalled talks with South Korea and the United States.

The latest test came a day after the United States mission to the United Nations, joined by France, Ireland, Japan, the United Kingdom, and Albania, issued a joint statement condemning last week's test.
