CAIRO -- Hundreds of Egyptians are marching toward Tahrir Square ahead of the one-year anniversary of the uprising that toppled longtime leader Hosni Mubarak.

The protesters set out from different neighborhoods in Cairo on Friday, which they have dubbed "the dream of the martyrs."

They say the families of hundreds of people killed during the uprising and the around 100 others that have been killed in clashes with the military rulers that took over from Mubarak have yet to get their "retribution."

Activists organized the rallies as part of a week of "mourning and anger" around the Jan. 25 anniversary to muster support for their call to end military rule. They say the ruling generals have continued the policies of the toppled regime.
