A procession of thousands snakes through the streets of Cairo.
This march, winding towards Egypt's state television building, marks the first anniversary of what's been dubbed the 'Maspero Massacre'.
On October 9 of last year, as mainly Coptic Christians demonstrated here over an attack on a church in Upper Egypt, military forces attacked the protesters.
Of at least 26 people who died, many were run over by armoured personnel carriers that smashed through the crowds seemingly at random.
An investigation was called following the killings and the then-military rulers promised justice.
But to date no one has been held to account, and demonstrators here are furious.
(SOUNDBITE) (English) EGYPTIAN DEMONSTRATOR, OMAR KAMEL, SAYING:
"As long as an oppressive regime - as long as the people working under an oppressive regime do not get punished and are not held accountable, they will continue to do exactly the same thing that they did for thirty years, and which caused the revolution to start in the first place. Justice needs to be executed."
Chants for the trial of former Field Marshal Tantawi also echoed through the crowds.
He led the ruling Supreme Council of the Armed Forces, which governed Egypt until President Mohamed Mursi took office last June.
