"WHO and partners finally managed to reach Kamal Adwan and Al-Sahaba hospitals yesterday after 9 attempts this past week," he posted on social media platform X.

"The missions were completed amid ongoing hostilities," he added.

He said drivers had been subjected to "humiliating security screening" and even temporarily detained at a checkpoint, "which is unacceptable".

The WHO regularly criticises Israel for the obstacles it puts in the way of these supply and patient evacuation missions.

It did so again on Friday during a news briefing in Geneva specifically on the subject of this relief mission to the northern Gaza Strip.

"One-off missions are not enough. There is a sustained need for resupplying hospitals to keep them functioning," Tedros said, reiterating his call "for sustained facilitation of humanitarian missions and ensuring safety for humanitarian staff; and for a ceasefire".

According to the WHO, 13 patients in critical condition were transferred from Kamal Adwan Hospital to Al-Shifa Hospital in Gaza City.

"The hospital is overwhelmed and still serving around 60 in-patients and receiving at least 50-70 injured daily," Tedros said.

Six other patients who had been transferred earlier from al-Awda Hospital to Kamal Adwan were also taken to Al-Shifa, along with those accompanying them.

The resupply mission also delivered 20,000 litres (5,300 gallons) of fuel to keep Kamal Adwan and Al-Awda operational, and 23,000 litres of fuel were delivered to Al-Sahaba Hospital, along with 800 units of blood and essential medicines and supplies.

The fuel is mainly used to run the hospitals' generators to ensure power supply.

The hospital infrastructure throughout the Gaza Strip is very fragile after a year of the Israeli genocidal war on Gaza, with many facilities having been hit by shelling or fighting.

Israel has killed at least 42,289 people in Gaza, most of them women and children, since it started the war on 7 October 2023.
