At least one corner of Daraya was hit by a more unorthodox weapon that is becoming more common by the day: the so-called "barrel bomb". Essentially an improvised bomb made of explosives stuffed into an oil barrel or similiar receptacle and pushed out of a helicopter, the weapon's seemingly Looney-Tunes origins conceals one of the most destructive and indiscriminate weapons in Assads arsenal. Packed with shrapnel and extra incendiaries like oil, and usually triggered on impact, the large payload all but guarantees widespread destruction.
