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 the Israeli military declares as Hamas's 'main stronghold'.

Witnesses report advancing tanks throughout the city center, with continuous air and artillery strikes and bombardments contributing to the escalating humanitarian crisis.

Al-Shifa hospital has become a symbol of the conflict's toll, with doctors lamenting the lack of resources as bed availability and medical supplies dwindle amidst heavy casualties.

Dr. Nada Abu Alrub described the grim conditions stating, It's just a mass murder, a killing, a torture, a nightmare. She recounted performing emergency surgeries on severely injured patients without adequate anaesthesia.

As the conflict rages on, more than 640,000 Palestinians have been forced to flee, with overcrowding in southern hospitals exacerbating the already critical situation.
