The order, issued Monday, targets union chief Yehia Qalash, Khaled al-Balshy and Gamal Abdel Rahim. It calls them to trial on June 4 in Cairo.
The controversial case stems from a May 1 police raid on the Cairo offices of the Egyptian Journalists Syndicate, where police aimed to arrest two opposition journalists who had sought refuge inside.
Days later, the union demanded a presidential apology and the release of all detained journalists, while threatening to strike if its demands were not met. Protesters spurred by the arrests also called for the removal of Interior Minister Magdy Abdel Ghaffar.
Monday’s order charging the union trio comes as authorities face rising public dissent against President Abdel Fattah el-Sissi, whom rights activists and diplomats inside and outside the country describe as increasingly authoritarian.
The rights group Amnesty International denounced the union leaders’ arrests, calling them “the most brazen attack on the media the country has witnessed in decades.” Amnesty’s Magdalena Mughrabi also said the arrests signal “a dangerous escalation of Egyptian authorities’ Draconian clampdown on freedom of expression.”
A lawyer for the union trio, Sayed Abu Zeid, told the Associated Press his clients were questioned for hours Sunday evening and that they initially refused to post bail because “publishing news … should not involve imprisonment or bail.” Prosecutors later said bail was posted.
