The World Health Organization (WHO) is trying to get access to Nasser Hospital as Israeli troops continue to raid the facility with thousands of trapped civilians, Al Jazeera reports.

“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 has called the raid on Nasser Hospital “precise and limited”, adding it detained dozens of “terrorists”, without providing any evidence.
