In this image taken from video obtained from the Shaam News Network, which has been authenticated based on its contents and other AP reporting, columns of smoke billow above houses as a result of heavy bombing in Damascus, Syria, Monday July 22, 2013. Syrian rebels seized a strategic village on the edge of the northern city of Aleppo on Monday, activists said, just hours after other opposition fighters sustained some of their heaviest losses in months in battles to the south near the capital, Damascus.
