North Korea has terminated any peace agreements made during the Korean War.
The signing of the original truce in 1953 was covered by Pathé News and the newsreel can be viewed here. The archive also has additional material from the Korean War, including combat footage. You can find a selection in this collection.
The conflict is often referred to as “The Forgotten War”, but as many as two and a half million civilians lost their lives during the fighting, as well as many British soldiers.
