Whoever it was (officially that is although most will know that this was Russia drawing a line in the sand) after their child-murdering pilot was liquidated like the dog he was by barefooted fighters as well as 100's of soldiers (casualties are huge in real life but hidden well, hackers have already exposed this - just like back in Chechnya were they lost 50.000 soldiers over a 10 year period). We will not know until some time from now but all 3 parties involved will claim it as "theirs". The biggest question is what took this long? 7 years of violations, bombings, killings and Al-Assad regime barking? The Nusayri was more busy mass-murdering his own people and destroying half of Syria for a few more years in power.
Still yet to reconquer the Golan Heights that his useless Nusayri mass-murdering father (Hafiz) lost due to his incompetence over 40 years ago. Nothing in the past 7 years. That's the biggest joke. Al-Assad regime apologists will of course make excuses now as well as ignore that in the past 3-4 days alone 300 civilian Syrians (half children) have been murdered by this Nusayri cancer. Looking forward to getting a ban once again for speaking the truth. Could not care less BTW and will just relocate to Arab forums and Reddit. As you can see Pakistanis, all Arab users in this thread (3 of us) wish hell to both for a reason. Go check Arab military forums out right now. We are having a field day.
LOL. Stronger than Pakistan. Sure. In a fantasy world. This is 100% the work of Russia. Not al-Assad or Mullah's. Have some shame.
