'Welkom in Orania' proclaims a mural, painted in white, blue and orange. But this South African town, in the remote Northern Cape province, does not extend its welcome to everyone. The colour scheme on the wall - accompanied by the community emblem of a boy pulling up his sleeves - harks back to the old apartheid flag. Orania, one of the last outposts of racial segregation, is a whites-only enclave. Around 1,000 people live in the rural community, established in 1991 during the last years of apartheid.
