In pictures: India's African communities

The shrine in Jambur houses the tomb of a saint known as Nagarchi Baba - Drum Master.

The Sidis say he was an Arab who visited Africa some 900 years ago, before settling in India.

The Sidis also worship another Sufi saint at the shrine, known as Bava Gor, a Nigerian bead merchant.

The priests are possessed by the spirits of the saints and bless the worshippers.
