Black Alert was the bulletin of the Anarchist Black Cross- South Africa (ABC-SA), a project that was linked to Bikisha Media Collective, Zabalaza Books and the Zabalaza Action Group (in Durban). These groups later merged into the Zabalaza Anarchist Communist Federation (later, Front) in May 2003: more on the ZACF here.
Both Black Alert and the ABC-SA continued to operate as a ZACF project.
The Anarchist Black Cross is an international anarchist prisoner support network, operating worldwide, dating back to the start of the twentieth century.
Issue 2 of Black Alert mainly comprised reprints of statements and appeals by South African community movements, mixed with some international material.
