Amid growing tensions in the peninsula, North and South Korea have marked the 57th anniversary of the armistice ending the Korean war.
In a show of unity, US and South Korean military chiefs held a ceremony in the demilitarised zone that divides the two Koreas.
The North has also been marking the ceasefire. But these are tense times.
Leader Kim Jong-il is angry about joint US and South Korean naval war games still being held in the peninsula.
Pyongyang insists the US started the Korean war in 1950 and depicts the armistice signed three years later as a victory.
Despite it’s recent rhetoric over the military exercises, the North has called for a full peace treaty as the two Koreas are technically still at war.
South Korean protesters also marked the ceasefire close to the North’s border. They released several large balloons containing anti-Pyongyang propaganda and US dollars.
Seoul and Washington blames Pyongyang for sinking of one of the South’s warships in March.
North Korea denies the allegations.
