Syrian opposition activists protest outside the venue of the main opposition National Coalition meeting in Istanbul on May 26, 2013. Angry at the Coalition's failure to reach any agreement, a group of some 15 protesters gathered outside the hotel where the group was meeting, with some demanding speedier action and others rejecting negotiations outright."We want them to decide. They've been in there four days, discussing expansion while they should be taking a stand against Iran and Hezbollah's attack on Qusayr. What are they doing?" said one activist from Daraa in the south. The Coalition, which depends on foreign backing, has long been marred by regional rivalries that play themselves out through disagreements among opponents. The Coalition in its current shape is dominated by main opposition bloc, the Syrian National Council, in which the Brotherhood plays a key role. OZAN KOSE/AFP/Getty Images ( 520089020 )
