Tens of thousands of people marched through the streets of Dakar on Sunday to mark the start of the annual World Social Forum. Activists carried colorful banners denouncing land grabs, restrictive immigration laws, agricultural subsidies in Europe and the US and many other issues. Others sang freedom songs and played drums whilst marching peacefully through the streets along a route that began near the offices of Senegal's public broadcaster, RTS, and ended at the Cheikh Anta Diop University, the main venue for the weeklong gathering.
