Protesters unhappy with the pace of change and the continued military rule in Egypt flooded Cairo's Tahrir Square over the weekend demanding civilian rule. Riot police responded with tear gas, beatings, and live ammunition, leaving at least 20 dead in continuing clashes. Egypt holds parliamentary elections next week, and demonstrators want presidential elections to be held shortly afterward. The ruling military has proposed to delay those elections until late 2012 or even 2013, angering Egyptians frustrated with the military's role in government. Collected here are images of the struggle over the weekend. -- Lane Turner (24 photos total)
