That would be the "hospitals" staff, the ones who said that it was absolutely not true that Hamas operated within the hospital complex. That there were absolutely no tunnels under the hospital. That 500 people were killed when the hospital was destroyed, when it was still standing and the actual death toll was, IIRC, 12 people who were in the car park?
N9w, I don't know whether the people speaking out claiming to be doctors at the hospitals are actually Hamas, or genuinely doctors who have been threatened by Hamas and told to lie, but I think it's safe to say that the reports coming out of "hospitals" are not to ba taken at face value.
