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.

South Korea and the United States will conduct major joint military drills starting on August 18, officials said, although they will delay parts of the annual exercises that have been a source of tension with North Korea to later in the year.

The United States and South Korea will kick off their Ulchi Freedom Shield large-scale joint military exercise this month, both countries announced Thursday.
