THOUSANDS from across the world will gather in Berlin this weekend to mark the 100th anniversary of the murder of revolutionaries Rosa Luxemburg and Karl Liebknecht.

Communists will lead a march to the Friedrichsfelde Cemetery in the east of the city and red roses will be placed on their gravestones in their memory.

The pair, who were leaders of the German Communist Party, were murdered by the right-wing reactionary troops known as the Freikorps on January 15 1919 by authorities keen to crush the growth of a revolutionary movement.
