In a speech to mark the 80th anniversary of Korea's liberation from Japanese colonial rule, Lee said he would restore the so-called September 19 Comprehensive Military Agreement, a de-escalation measure that halted some military activities at the border between North Korea and South Korea.

South Korean President Lee Jae Myung pledged to "respect" North Korea's political system and said Seoul would not seek unilateral reunification in a speech to mark Liberation Day.

Seoul, South Korea - 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.
