My man, you’re sourcing rabidly pro-Israel sites, and Twitter.
I’ve seen the same footage, but I don’t recall seeing Hamas confetti come out of the explosion.
Yes, it’s entirely possible Hamas planted that bomb, but ascribing attribution with certainty is an impossible task at this point.
Feel free to point out the valid question, but for your own sake, don’t automatically assume that “facts” from a warzone that are made readily available are somehow automatically credible.
