Three U.S. students have been arrested in Cairo for allegedly throwing firebombs at Egyptian security forces amid ongoing anti-government protests. The Americans attend the American University in Cairo as exchange students. The school, which sits on Tahrir Square, the central protest site, confirmed the students' arrest. National television showed video of the three, identified as Derrik Sweeney, from Georgetown University, Luke Gates, from Indiana University and Greg Porter, from Drexel University. Kevin Sweeney, Derrick's father, told CBS Radio news that his son was being held in a courthouse in Cairo.
