Doctors at one of Gaza City's last functioning hospitals say they are overwhelmed with casualties from Israeli strikes and are having to carry out operations in filthy conditions with few or no anaesthetics.

One Australian medic volunteering at al-Shifa hospital told the BBC that every day was a mass casualty event, while another described how a baby had been saved from the body of a pregnant woman who had been killed.

Israeli forces are now just 500m (1,640ft) away from the hospital as they expand their ground offensive to fully occupy Gaza City, which Israel's military calls Hamas's 'main stronghold'.

Witnesses report tanks advancing into the city's center from the south and north-west, further exacerbating the crisis.

Israeli air and artillery strikes, attacks by quadcopter drones and detonations of remotely driven vehicles laden with explosives continue to displace tens of thousands of Palestinians each day.

The Israeli military claims the offensive aims to defeat Hamas and recover hostages taken during earlier fighting.

Al-Shifa hospital, once the largest medical facility in the Gaza Strip, lies in ruins with burned wards and insufficient medical supplies. Doctors recount harrowing stories of treating patients without adequate anesthetics and performing life-saving surgeries in appalling conditions. Emergency surgeries have become a routine, with numerous trauma cases arriving each hour.

Reports indicate that Israeli tanks are rapidly encroaching on populated areas, forcing thousands of Palestinians to flee their homes. As evacuations continue, logistical challenges complicate efforts for families seeking safety.
