On 9 December 2023, a WHO team, in collaboration with the Palestine Red Crescent Society (PRCS) and the United Nations Office for the Coordination of Humanitarian Affairs (OCHA), and with support from the United Nations Department of Safety and Security (UNDSS), completed a high-risk mission to Al-Ahli Hospital in Gaza City to deliver medical supplies, assess the situation in the hospital, and transfer critically-injured patients to a hospital in the south. The mission delivered trauma and surgical supplies, enough to treat 1500 patients, to the hospital, and transferred 19 critical patients with 14 companions to Nasser Medical Complex in south Gaza, where they can receive a higher level of care.
On the way north, the UN convoy was inspected at the Wadi Gaza checkpoint, and ambulance crew members had to leave the vehicles for identification. Two PRCS staff were detained for over an hour, further delaying the mission. WHO staff saw one of them being made to kneel at gunpoint and then taken out of sight, where he was reportedly harassed, beaten, stripped and searched.
