Dunno, saw it too. But Ahrar is denying it on their official accounts. Nusra just published some video´s of random mortar shelling on the city, but not much that looks like a fool out assault.
I find this a very interesting battle, as some people on Twitter were suggesting that the Hezbollah and Afghani Shia militia's attacked without order or supervision of the Assad regime or the IRG planners, and thus led heavy losses. I kinda would agree on this theory, certainly cause the amounts of dead regime soldiers in that failed offensive to break the siege of Zaraa and Nubil was so high, unusual high. I saw some video's posted on rebels their facebook's of Assad soldiers just being picked off one by one from rebel trenches, no tank or air support at all.Like before trying to recapture other towns to the north they should take Tal Jibbin not to create and overextented position with a single supply route, as what happened last time they pushed to Hardatnin without securing this town...
