Yes, publically available truth does not exist for this claim, which is why Snopes doesn't even have to rate it.

The fact that this is a woman who speaks truth to power saying it, a woman who hates lies and hates to lie, versus the Zionazi state...they obviously don't take that into account, because of what ScaredExcrement has correctly pointed out.

They'd give it a 'half true' if Israel showed photos of the torture, because they wouldn't be able to verify that it wasn't a photo op.
