Angola’s President João Lourenço has apologised to victims and families of those killed in the May 1977 massacre and asked for forgiveness on the government’s behalf. The BBC reports that thousands, including many of the country’s young intellectuals and party activists, were imprisoned, tortured and killed following a split in the governing People’s Movement for the Liberation of Angola (MPLA) party. Amnesty International says 30,000 died in the purge. Some say as many as 90,000 were killed. In his address to Angolans, President Lourenço termed the killings by government forces as a “great evil”.
