Gaza City's Al-Shifa Hospital

World leaders have called for an investigation and a ceasefire nearly five months into the Gaza war after dozens of desperate Palestinians were killed rushing an aid convoy.

Israeli forces stormed Gaza's largest hospital Wednesday, targeting what they believe is a Hamas command centre housed among thousands of ailing and sheltering civilians.

Israeli and Palestinian officials said military operations were taking place at Gaza City's Al-Shifa hospital — the focal point of days of deadly fighting and nearby aerial bombardments.

With tanks massed at the gates of Gaza's largest hospital, US President Joe Biden pressed Israeli allies to protect civilians, who on Tuesday were trapped inside with dwindling supplies of fuel and water.

A Turkish medical delegation on July 9 began carrying out surgical operations for Palestinian patients in Gaza City's Al-Shifa Hospital.
