"That Mr Mubarak and his sons are to stand trial is a very welcome step but all those found responsible for the killings and other human rights violations, such as torture, must face prosecution and must be held accountable," the statement said.
It added that the trial must offer the victims and their families the chance to confront the defendants and get answers. "This is a unique opportunity for truth to be revealed and justice to be seen to be done in Egypt," Amnesty said.
The rights group said that the families of those killed during protest violence had a right to justice as do all those who were seriously injured or subjected to arbitrary detention or torture.
