sourceAFRICA is the continent's largest repository of documentary evidence and other "actionable documents" from investigative journalists and civic watchdogs. Forked from DocumentCloud.org, and built on the Ruby on Rails framework, the project is accessible here: https://sourceafrica.net/
A lot of the embeds still point to DocumentCloud assets that could cause issues in embedding.
