TOPSHOTS Egyptian protesters look at riot police through gaps in a wall standing for a security barrier near Tahrir Square as they try to dismantle it during a protest to call for the fall of Islamist President on January 24, 2012 in Cairo. A few dozens men and youths tried to dismantle the wall of concrete blocks that blocked a street leading to Tahrir Square, focal point of demonstrations that broke out on January 25, 2010 and led to Mubarak's resignation 18 days later.
