North Korea intentionally released a wall of water from a dam which caused a deadly flash flood south of the border, a South Korean minister said Wednesday.
Sunday's massive discharge of water into a cross-border river swept away six South Korean campers and stirred anger in the South.
The incident threatens to damage cross-border relations which had lately been improving.
Asked if the discharge was intentional or a mistake, Unification Minister Hyun In-Taek told parliament: "I think the North did it intentionally."
Hyun was the first South Korean official publicly to assert that the release of the water was intentional.
