The powerful sister of North Korean leader Kim Jong Un on Thursday dismissed South Korean claims that the North is removing some of its loudspeakers along the inter-Korean border, mocking the government in Seoul for clinging to hopes of renewed diplomacy between the war-divided rivals.

SEOUL, South Korea (AP) — South Korea’s military said Saturday it detected North Korea removing some of its loudspeakers from the inter-Korean border, days after the South dismantled its own front-line speakers used for anti-North Korean propaganda broadcasts, in a bid to ease tensions.

The military said further confirmation was needed on whether the dismantling was taking place across all areas.
