Egyptian riot police throw stones during clashes with protesters near the interior ministry in downtown Cairo, Egypt, Sunday, Nov. 20, 2011. Firing tear gas and rubber bullets, Egyptian riot police on Sunday clashed for a second day with thousands of rock-throwing protesters demanding that the ruling military quickly announce a date to hand over power to an elected government. The police battled an estimated 5,000 protesters in and around central Cairo's Tahrir Square, birthplace of the 18-day uprising that toppled authoritarian leader Hosni Mubarak in February. (AP Photo)
