"There are still critically injured and sick patients that are inside the hospital," WHO spokesperson Tarik Jasarevic said.
"There is an urgent need to deliver fuel to ensure the continuation of the provision of life-saving services... We are trying to get access because people who are still in Nasser medical complex need assistance."
Israel's military called the raid on Nasser Hospital "precise and limited" and said it was based on information that Hamas were keeping hostages in the facility, with some bodies of captives possibly there.
