Someone did but it could still be claimed to be “accidental” if that information didn’t make it to the person performing the attack. I’m not saying that’s what happened but it’s plausible. Though I will say at minimum I doubt they would have done this if they knew how well connected these aid workers were. It would have been politically very foolish.
I think their overall strategy makes it clear that they don’t much care to avoid killing civilians and aid workers that are not well connected. But it’s hard to prove it’s done intentionally.
