In this Sunday, Oct. 28, 2012 photo, rebel fighters belonging to the Liwa Al-Tawhid group keep an eye over their enemy's position as they prepare to open fire as mortar explosions and gunshots are heard in the nearby battlefield in the Karm al-Jabel neighborhood of Aleppo, Syria. Syria's air force fired missiles and dropped barrel bombs on rebel strongholds while opposition fighters attacked regime positions, flouting a U.N.-backed cease-fire that was supposed to quiet fighting over a long holiday weekend but never took hold.
