A doctor believed to be the last remaining orthopaedic surgeon in northern Gaza has been killed by Israeli tankfire, according to Palestinian officials.

Dr Sayeed Joudeh died on Thursday while he was on his way to work.

He was a surgeon at Kamal Adwan and al-Awda hospitals in northern Gaza.

The Israeli military said it was unaware of the incident, but it was investigating.

The grandfather had come out of retirement to help during the war.
