Aleppo "Barrel Bombs Massacre"

In mid-December, 2013, daily reports out of Aleppo claimed a remarkable number of civilian deaths from increased aerial bombardment with explosive barrels. These powerful devices have been used, complained about, and blamed for various atrocities for some time, but this bombing (or propaganda?) campaign is the most acute underlining of the issue yet. By December 29th there were reports that over 517 people had been killed so far in these attacks by the Syrian military. This page (and its talk page) will be dedicated to collecting these reports, and examining the evidence behind them, and related issues.
