The border between North and South Korea remained calm on Wednesday amid North Korea's strong warning against South Korea's annual Hoguk military exercise.
A North Korean soldier stood in front of the Panmungak building, directly facing South Korean soldiers.
No unusual movement was reported from the area.
South Korea started its 12-day Hoguk (Safeguard) exercise on Monday.
This is a nationwide joint military exercise involving the Army, Navy, Air Force and Marine Corps in preparation for military action by North Korea.
The South Korean Defence Ministry has said that this year's exercise will involve about 330-thousand troops, the largest number since the it started in 1996.
North Korea's Secretariat of the Committee for the Peaceful Reunification of Korea released a statement on Wednesday stating that the South "clearly proved that it does not hope for dialogue, but has attempted to use it as a camouflage in order to escalate confrontation and war moves."
"The army and people of the DPRK will mercilessly wipe out the South Korean puppet forces if they provoke the DPRK even a bit," warned the statement.
The Korean Peninsula remains in a technical state of war because the 1950-53 Korean War ended with an armistice, not a peace treaty.
About 28,500 US troops are stationed in South Korea to help deter potential aggression from North Korea.
