such claims by one of the parties to the war (especially a party with such a long history of lying about it) are insufficient justification for attacking a hospital, doctors, journalists, etc
otherwise hamas could claim with at least as much credulity that every innocent person they killed just happened to be beside a soldier and they just missed, oops, so it's all good right?
or they could claim with at least as much credulity that there were no combatants launching attacks from the hospital, and that would cancel out israel's claims that there were, and thus israel's claimed justification
yes: absent independent investigation and judgement, there is no credible justification for this attack on civilians
of course, this is to say nothing of morality: killing innocent civilians and their press for exercising their right to video their own land? gross.
killing the rescuers and doctors and reporters who responded to your first killing (and were within their rights to do so)? sick.
genociding hundreds of thousands of innocent palestinian civilians to avenge a thousand israeli ones because you think israeli people are superior and more valuable than palestinian people? literally atrocious.
