The two Koreas on Monday started to remove landmines along a section of their heavily fortified border as part of a summit deal to ease military tensions, Seoul said. The agreement between the nations — which are technically still at war — was reached at a meeting in Pyongyang last month between South Korean President Moon Jae-in and his North Korean counterpart Kim Jong Un. Both sides undertook to carry out landmine removal work at the Joint Security Area (JSA) over a 20-day period, according to the South Korean defence ministry.
