Three Al Jazeera English journalists have been imprisoned in Egypt since 29th December 2013.
They have suffered harsh conditions, solitary confinement, denied medical treatment and are now on trial for charges related to terrorism, along with six other foreign journalists being tried in absentia.
Peter Greste, Mohammed Fahmy and Baher Mohamed, who were simply doing their jobs, are being tried in Cairo, charged with terrorism-related offences and "spreading false news".
Another Al Jazeera Arabic reporter, Abdullah Al-Shami, has been in prison since August 14 and has been on hunger strike for more than 30 days.
And they are not the only press to be incarcerated by the Egyptian authorities.
Journalists are not terrorists. They risk their lives to shed light on abuse, suffering and injustice around the world. They are our eyes and ears, as well as our voices. An attack journalism is an attack on everyone who values the freedom to speak their minds and know the truth.
Please join the world's press in a Global Day of Action on Thursday 27th February with peaceful demonstrations, silent protests and individual images that will send a message to Egypt and the world: if you silence the press, you silence us all.
