"On June 15, dozens of blue metal gas canisters fell from the sky and slammed into the streets of western Aleppo, Syria. “It was raining gas canisters,” remembers one shopkeeper. Locals here know them well and call them jarra. Filled with nails, ball bearings and crude explosives, the modified domestic propane cylinders are fired from homemade howitzers the rebels have dubbed “hell cannons” and have a range of less than a mile." "The armed rebels in eastern Aleppo are now arranged in two weighty coalitions; one loosely associated with the Free Syrian Army, elements of which are supported by the United States, and the other dominated by Al-Qaeda. But it’s not so easy to separate the good guys from the bad guys in Syria; it was Free Syrian Army battalions that perfected the jarra."
PS I think this is the first article I have read in the Western press about "Artillery of Hell".
