A taxi driver looks out from his car in front of defaced images of U.S. President Barack Obama with Qatar’s Emir Sheikh Hamad bin Khalifa al-Thani (C) and Turkey’s Prime Minister Tayyip Erdogan (R) in downtown Cairo March 25, 2015. Arab leaders meeting at a summit this week face rapidly deteriorating conflicts in Yemen and Libya, but have yet to agree on a concrete plan to counter a growing threat from Islamist militant groups and regional chaos. The poster reads: “Obama the biggest supporter and producer of terrorism in the world.” REUTERS/Mohamed Abd El Ghany
