Don't know... maybe the same kind of propaganda bullshit we always hear in such conflicts.
Oh, wait. No. Because they don't need to when Israel is indeed contradicting itself constantly and links to sources and screenshots of quickly deleted official social media post are entirely sufficient without needing to spin the story...
Wouldn't be surprised if Israel did it and covered it up. Wouldn't be surprised if the Palestinians accidentally blew it up or did it on purpose. No way of knowing. Everyone involved is gonna lie.
I'm not entirely discounting the possibility that it was a Hamas rocket accident, but claiming that an Israeli attack on Gaza was actually a hamas misfire is SOP for the IDF. The idea that hamas would do this intentionally is absurd though.
