Kim Jong-UnNorth Korean leader Kim Jong Un
apologised on Friday over the killing of a South Korea
official near the rivals' disputed sea boundary, saying he's “very sorry” about the incident he called unexpected and unfortunate, South Korean officials said.
Kim's move will likely de-escalate tensions between the Koreas as it's expected to ease anti-North sentiments in South Korea
over the man's death as well as mounting criticism of its liberal President Moon Jae-in.
