North Korea on Friday fired a short-range ballistic missile, conducted an artillery barrage, and flew fighter jets close to the South's border in another show of force that the US has warned could culminate in a nuclear test.
Pyongyang has dramatically ramped up missile launches and military exercises in recent weeks, which it now describes as "tactical nuke" drills, as Seoul and Washington say Kim Jong Un is close to conducting what would be his country's seventh nuclear test.
