The WHO said on Sunday that it had documented more than 100 attacks on the healthcare system in Gaza, as the Israeli military said Hamas fighters were using two additional hospitals in the enclave to conceal their operations. A week after Israeli officials said they had identified Gaza's largest hospital al-Shifa as being used by Hamas for underground command centres, the military's chief spokesman Rear Admiral Daniel Hagari presented images and videos of what he said was the opening to a Hamas tunnel under Sheikh Hamad Hospital, north of Gaza City.
