Distinguished by their dark skin, Yemen's 'untouchables', who prefer to be called the marginalised ones, are a caste languishing at society's lowest social order.
Named the Akhdam, an Arabic word for servant, they are confined to living in slums and working menial jobs, with no regard given to their basic human rights.
Activists and community leaders are fighting to eliminate stereotypes and destroy the stigma that surrounds them.
