An Egyptian rights group has accused the country's authorities of failing to bring to account those responsible for the deaths of 26 Coptic Christians killed during an anti-government demonstration one year ago.

Copts and political groups are holding a rally Tuesday on the anniversary of the deadly protest, during which armored personnel carriers ran over anti-government demonstrators. They want the military rulers that were running Egypt at the time to be put on trial.

The Egyptian Initiative for Personal Rights says a "flimsy sentence" against three soldiers for the deaths of 15 of the protesters doesn't bring to account those ultimately responsible for the violence.

Lawyer Hani Ramsis says a complaint against some of the generals who were ruling Egypt at the time was filed to the civilian prosecutor Monday.
