Israeli attacks have killed 500 health workers in Gaza since October, including several specialised doctors, Al Jazeera reports according to the AP news agency reports.

The specialist doctors killed include a plastic surgeon specialising in wound care, a reconstructive surgeon, an obstetrician/gynaecologist, an orthopaedic surgeon, a fertility doctor and the only liver transplant doctor in Gaza.

Hassan Hamdan, a plastic surgeon who specialised in wound reconstruction, was killed along with 12 members of his family earlier this month after coming out of retirement to help during the bombardment.

His son Osama Hamdan, an orthopedic surgeon was on duty in the emergency room at Nasser Hospital when he received the call. His wife and two sons — 3 and 5 years old — were among those killed.

“I was only able to collect some body parts of my kids and their mother because of how huge the explosion was,” he said.
