Earliest date found for this image [via Tineye] is 1 April 2014 with this caption:

Left After Assad Bombing in Aleppo.

I have a bit of a problem with that structural impossibility, and so does physics. Then I found this:

That image dates to 23 March 2014. A more recent post dated 19 June 2015 comes from TehranPress.com. Even Google Translate can’t crack that one, but it appears that someone’s laughing.

This seems to be the unadulterated version, with an interesting caption:

Residents try to find their belongings among the rubble left of their homes after what activists said was an air attack from forces loyal to Syria’s President Bashar Al-Assad in Bab Neirab, Aleppo, on July 27, 2013.

That caption and image came from The Atlantic via *ahem* Reuters… who have never *cough* posted manipulated propaganda photos before.
[Hint: Google Islamic Rage Boy, Green Helmet Man, Wailing Woman, Iraqi Missile Photoshop.]

Yet even the description (“what activists said”) sounds specious. When Assad was under attack by the Muslim Brotherhood, why would his forces bomb his own people, unless Syria was already infiltrated by radical islam?

Oh, wait…

[Top image found here entirely by accident, and the others didn’t come from Little Green Footballs either.]
