The government of Chad announced Thursday it would open an inquiry after Facebook said it had closed down fake accounts used by Russia and France in a battle for influence in Africa. The US tech giant said on Tuesday it had closed down two Russian-linked networks of accounts and a third with “links to individuals associated with French military” for breaking its policy against foreign or government interference. The networks aimed at swaying opinion in countries in North Africa and the Middle East, including Chad. In a statement, Chadian spokesman Mahamat Zene said the government “condemns these attempts to manipulate African public opinion or discredit sovereign nations.” The government “has asked the appropriate authorities to open a judicial inquiry into persons unknown,” he said. Chad’s National Computer Security and Electronic Certification Agency (ANSICE) is also making itself available to collaborate with Facebook “about frustrating such operations, which harm the interests of several countries,” he said. Facebook said the troll accounts aimed at influencing users about French and Russian activity in Africa.
