Dozens of activists have demonstrated in Morocco's capital in a rare protest against racism following the murder earlier of a Senegalese migrant.

Thursday's protest comes just one year after Morocco announced a new more humane policy designed to deal with the flood of sub-Saharan Africans seeking a new life in Europe.

Charles Ndour was fatally stabbed on Aug. 30 by a mob in Tangiers. Police later arrested and deported more than 20 immigrants protesting his killing.

Lucile Daumas of Atac Maroc, one of the groups organizing the demonstration, said Ndour was the sixth immigrant killed in the last year, amid many such attacks.

"The migrants in Morocco are in real danger," she said.
