South Korea will end some military activities along its border with North Korea, President Lee Jae Myung said on Friday, in his government's latest effort to improve ties between the neighbouring countries still technically at war.

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.
