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.

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

Al-Shifa hospital was once the biggest medical complex in the Gaza Strip. It now lies in ruins, pockmarked by craters, with burned-out wards and bullet holes.

Many of the beds do not even have mattresses, medicines are in short supply and the casualties are endless. Dr. Nada Abu Alrub, an emergency specialist volunteering at the hospital, described the appalling conditions, saying they operate on severely wounded patients with minimal to hardly any anaesthesia.

The violence has forced around 640,000 Palestinians to flee, while the health ministry has reported at least 65,382 fatalities since the onset of the latest conflict.

As the fighting continues and hospitals are overwhelmed, the humanitarian crisis deepens, leaving many to face unimaginable hardships amid the chaos.
