Amira Al Hussaini reports for Global Voices that Twitter has been blocked in Egypt, apparently in an attempt to disrupt political activity. From tweets Al Hussaini curated, it appears that the communications blockade may be broader than just the microblogging service as the Mubarak regime endeavors to quell dissidents.
Such censorship has sparked the anger of activists, especially since it is the first time in Egypt's history that such heavy-handedness is used to silence people online. The move is a stark reminder of the iron fist with which ousted Tunisian strongman Zeine El Abidine Ben Ali clamped down on the Internet, in neighbouring Tunisia, whose uprising has inspired millions of Arabs.
