This June 12, 2012, photo shows a Syrian revolutionary flag waving atop a building on the outskirts of Aleppo, Syria. Syria's conflict is the most violent to emerge from last year's Arab Spring. The protests started peacefully but prompted a brutal crackdown by President Bashar Assad's government. The fighting has escalated into a civil war that has killed more than 30,000 people over the last year and a half, according to activists. Despite intervening in Libya, the United States has steered clear of taking military action or arming Syria's rebels. (AP Photo/Khalil Hamra, File)
