Early on Wednesday, Mosireen, a media collective in Cairo, added a short report on the activist blogger Alaa Abd El Fattah to its YouTube channel. Mr. Fattah, who blogs as @Alaa, was arrested in October after he wrote that Egypt’s military rulers were responsible for the deaths of Coptic Christian protesters during a demonstration in Cairo that month. He was taken into custody for refusing to acknowledge the authority of the military prosecutor who had placed him under investigation. The blogger appeared in court on Monday, to hear that his request to be released from detention had been turned down by the authorities. Because his appeal failed on Monday, Mr. Fattah was not present on Tuesday when his wife and fellow blogger, Manal Hassan — @Manal — give birth to their first son, who was named Khaled, in memory of Khaled Said, an Egyptian whose death at the hands of police officers led to a Facebook campaign for justice that helped spark the Egyptian revolution. The video has no narration, but simply shows Mr. Fattah with his wife, mother and friends in court on Monday (in footage that was filmed secretly) and then the scene the next day, after the birth of his son. As some of his fellow bloggers have noted, the birth of Mr. Fattah’s child while he was in detention continues something of a family tradition. Mr. Fattah’s sister Mona Seif, a leader of the campaign to end military trials for Egyptian civilians who blogs as @Monasosh, was born while her father, a human rights lawyer, was in jail for his activism.
