North, South Korea and the UN completed the work of withdrawing military posts, armed troops and firearms from the Joint Security Area (JSA) in the buffer zone separating the two Koreas today.
Earlier the area was de-mined under UN observation and declared mine-free.
On Friday and Saturday, the three sides will carry out joint verification work to ensure that the JSA is completely disarmed, South Korean media reported based on a MoD statement.
"The military authorities of the two Koreas and the UNC will make joint efforts to ensure that the JSA disarmament, stated in the Sept. 19 military agreement, will be implemented normally," the ministry statement said.
Citizens of the two Koreas and foreign tourists will be allowed to cross the military demarcation line once the disarmament is complete. The South and North will each station a patrol of 35 unarmed soldiers, including five officers, there.
The two Koreas agreed to disarm the JSA under the military agreement their countries' defense chiefs signed during the third summit between President Moon Jae-in and the North's leader Kim Jong-un in Pyongyang last month.
