You have her statement of what she saw, even to the extent of her witnessing Israeli bulldozers burying the, just as you have with everyone else who has provided evidence that is contrary to Israel's account.
Yes we have her account.
She saw bulldozers clearing an area at the edge of the camps.
That is where defended and fortified buildings would have been.

The building she was describing is the one used by the Israelis as a headquarters – the soldiers were able to witness every detail of the massacre and did nothing.
No.
That building was a mile from the edges of the camp.
No-one could observe into the narrow maze of streets in the vast sprawling camps from there.

She herself had seen no signs of the civilian massacre from the top of her hospital deep within the camp, or during her long walk out.
