Israeli forces entered the compound of northern Gaza’s Kamal Adwan Hospital and opened fire after days of laying siege to the facility, health authorities in the enclave said.

Dr Hussam Abu Safiya, the hospital director, said in a video that Israeli tanks and bulldozers entered the hospital compound late Thursday and began firing at parts of the complex, adding that “all departments of the hospital are under direct shelling.”

“Instead of receiving aid, we are receiving tanks,” he said.

Kamal Adwan is one of three minimally operational hospitals in northern Gaza, and the closest to Israeli military activity in Beit Lahiya and the Jabalya Refugee Camp. Despite its limited capacity, it has been receiving most of the injured from the surrounding fighting.

World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus said on Friday that since the raid on Kamal Adwan hospital, WHO has “lost touch with the personnel there.”

“This development is deeply disturbing given the number of patients being served and people sheltering there,” Ghebreyesus said on X. Prior to Friday’s raid, he said, WHO and its partners managed to reach Kamal Adwan “amid hostilities in the vicinity, and transferred 23 patients and 26 caregivers to Al-Shifa Hospital.”

The Israeli military said in a statement Friday that its forces are operating in the area of the Kamal Adwan Hospital “based on intelligence information regarding the presence of terrorists and terrorist infrastructure,” adding that in the weeks preceding the operation, “the IDF facilitated the evacuation of patients from the area while maintaining emergency services.”

COGAT, the Israeli agency that manages the flow of aid into the strip, said on Friday that with the help of UNICEF and WHO, several patients and their escorts were evacuated from the facility. The hospital was also given fuel, blood units and medical equipment.

But WHO’s Ghebreyesus stated on X that the hospital is housing about 200 patients, along with hundreds more seeking shelter there.

‘Shocked by the entry of bulldozers and tanks’

Shamiya said that the military had entered the hospital yard for a second time on Friday morning and had begun separating men from women.

“After that, it became impossible to communicate with anyone.”

In his video message, Safiya said he was “shocked by the entry of bulldozers and tanks into the hospital compound,” adding that tanks began firing at the upper floors, shattering windows and “creating an atmosphere of panic, terror, and fear.”

“Everyone in the hospital gathered in the stairwell; it was a very distressing scene,” he said.

One video showed Abu Safiya speaking from within the Intensive Care Unit, where patients and medical staff were huddled. He said that some severely injured people were dying. Abu Safiya said that a number of properties around the hospital had been set on fire.

Later Thursday night, a convoy of supplies from the World Health Organization reached the hospital, he said. Video showed a fuel tanker and other vehicles close to the facility.

Abu Safiya said the convoy delivered enough fuel for five days, as well as 200 units of blood and a few other supplies, but no food or water.

He said he had been in touch with Israeli officers.

“I explained the situation of the patients and the injured people in the hospital, emphasizing that their condition was extremely critical and that evacuation was necessary.”

“We have no medical assistance that can reach them, and I do not have the means to help them even if they were able to reach us. We have nothing to offer them.”

It has been 21 days since Israel ramped up its military operation in northern Gaza. Authorities in Gaza say the military has stopped aid from reaching parts of the area and displaced many of its residents. Israel says it is preventing Hamas from regrouping.
