Echoing some of President Donald Trump’s rhetoric, authorities in Egypt are taking aim at an alleged barrage of “fake news” they say is meant to sow division and undermine the rule of general-turned-president Abdel-Fattah El-Sisi.Under a new law, the state’s top media regulatory agency can now use the “fake news” label to shut down social media accounts with more than 5,000 followers, without having to obtain a court order. Another new law allows blocking websites with content deemed a threat to national security.Last month, the government set up a unit tracking alleged rumors, after El-Sisi claimed without elaborating that the government had identified some 21,000 rumors having been circulated over a three-month period this year. The Cabinet often issues statements refuting purported rumors.Government critics denounce the measures as the latest attempt to suppress dissent and silence what is left of independent journalism. Over the past few months, some 500 online sites have been blocked, as part of the state’s growing control over the media, according to an Egyptian watchdog, the Association for Freedom of Thought and Expression.In recent years, more restrictive media policies have been adopted elsewhere in the Arab world as governments crack down on social media content.The Palestinian self-rule government, for example, last year clamped down on social media and news websites — main outlets for debate and dissent in the West Bank — with a vaguely worded law that allows for charges of harming “national unity” or the “social fabric.”In Egypt, officials have pointed to several recent reports on social media networks that they said were blatantly false and seemed designed to spread panic.
