The descendants of South Africans who perished on the troopship SS Mendi have called on international powers to give more recognition to them.

A total of 646 men died, most of them members of the South African Native Labour Corps, when the Mendi sank in the English Channel in 1917.

They were on their way to join the allied forces in Europe during the First World War, or Great War.

Sunday marks the centenary of the end of the global conflict.

One of the ceremonies held around the world was at the Union Buildings in Pretoria.

Dakile Ndamase, the grandson of one of the men who died on the SS Mendi, laid a wreath.
