CAIRO -- Scuffles have broken out between protesters and men armed with knives on the street leading to the military headquarters in Cairo.
Witnesses say the chaos erupted when men standing in front of army barricades began throwing stones at the protesters, who threw stones back at them. The demonstrators are angry at the military rulers who took over control of the country after a popular uprising forced ex-President Hosni Mubarak to step down more than five months ago.
One of the protesters, Selma el-Dahab, says Saturday's rally was attacked from the front.
