Three feeder columns of the annual Long March to free Kurdish leader Abdullah Ocalan, which started in Geneva, Frankfurt and Luxembourg, are converging on Strasbourg, France.
Ocalan, a leader of the Kurdistan Workers' Party, has been held in solitary confinement in a Turkish prison since 1999.
Below are some photos from the International Solidarity contingent of the Long March, which includes people from Australia, Ecuador, South Africa, Catalonia, Canada, the United States, Euskadi, Aragon, Asturia, Spain, the Canary Islands, Italy, Sweden, Norway and Portugal.
