In this Tuesday, Sept. 4, 2012 photo, a shirt and an AK-47 of a rebel fighter hang on a wall inside their headquarters in Marea, on the outskirts of Aleppo, Syria. Arabic reads on the wall from right, "God is great, the black panther, Alhassan Abu Nawras, Abu Mahmoud, Abu Ahmad, Abu Walid, Abu Mohammed, Abu Alfoaz." Rebels have taken a major stride in uniting their ranks in the battle for Syriaís largest city, giving them hope they could tip the balance in three-months of bloody stalemate in Aleppo, one of the biggest prizes of the civil war.. The question is how much more destruction the city can bear. Regime troops are retaliating with heavier bombardment, and civilians are bearing the brunt, their neighborhoods left in rubble.
