South Korea marks the 60th anniversary Friday of the three-year war with the North. The conflict ended with a truce in 1953 and the Korean peninsula has remained in an uneasy state between war and peace.

At a subdued ceremony in an Olympic gymnasium, South Korea paid tribute to its soldiers and allies who fought under the banner of the United Nations.

Combat and support units from 21 countries arrived after North Korean forces crossed into the South on June 25, 1950.
