An Egyptian protester carries a placard that reads in Arabic, "the people wants to dissolve the constituent assembly," and sets fire to a picture of judge Hossam El Gheriany, chairman of the constituent assembly, during a protest in front of the State Council's headquarters in Cairo, Egypt, Tuesday, Oct. 9, 2012. Human Rights Watch on Monday urged the panel writing Egypt's new constitution to amend articles in the draft that the New York-based group says repress the rights of women and children and limit freedom of religion and expression.

CAIRO — Several thousand Egyptians have marched nearly seven kilometers (four miles) through Cairo to demand retribution for 26 Coptic Christians killed during an anti-government demonstration last year.

Muslim clerics, Christian priests, activists and former liberal lawmakers were among those marching to mark the anniversary of the "Maspero massacre," referring to the name of the state TV building, where the clashes broke out.

The Christian-led protest a year ago began peacefully but turned violent. Military vehicles ran over protesters and gunshots were fired.

On Tuesday, protesters held a mock Pharaonic funeral, waving Egyptian flags with the Muslim crescent and Christian cross in a show of unity.

People chanted slogans calling for the execution of Field Marshal Hussein Tantawi, the military ruler at the time, who led Egypt through a tumultuous 17-month transition.
