Africa Check verifies news stories and claims made by public figures and institutions. (Similar to other fact-checking sites such as Politifact and Snopes.)
News verification reports often bring together multiple kinds of evidence to examine a claim. These can be useful for pointing you to relevant sources.
"Devised by the non-profit media development arm of the international news agency AFP, Africa Check is an independent organisation with offices in Johannesburg, Nairobi, Lagos, Dakar and London, producing reports in English and French testing claims made by public figures, institutions and the media against the best available evidence."
