Journalists in Kenya have staged a protest at the Egyptian Embassy against the imprisonment of reporters in Cairo.

Nearly 100 journalists and supporters took part in a march and demonstration Tuesday. Robin Kriel, co-chair of the local foreign correspondents association, delivered a letter and met with the deputy ambassador.

The protesters called for all journalists jailed in Egypt to be freed but focused their attention on Peter Greste, a Nairobi-based correspondent for Al Jazeera who has been in custody since Dec. 29. Twenty journalists working for Al Jazeera face charges of joining or aiding a terrorist group and endangering national security.

Three men working for Al-Jazeera — Mohammed Fahmy, a Canadian-Egyptian, Baher Mohamed, an Egyptian, and Greste — were arrested on Dec. 29 in a Cairo hotel.
