The head of the World Health Organization (WHO) warned that Israel's ground operations and new evacuation orders are expanding Gaza's health system.

Indonesians in Indonesians in the northern towns of Beit Lahia and Jabalia, Kamal Adwan and Al-Awda hospitals were in the evacuation area announced Tuesday, Dr Tedros Adhanom Ghebreyesus said. The other two hospitals are within 1 km (0.6 miles) of them.

He added that Kamal Adwan was suspended for hostilities due to nearby hostilities and that Indonesian hospitals were unable to access due to the presence of surrounding Israeli forces.

The Al-Awda Hospital is still operating, but its director told the BBC on Wednesday that it was “completely besieged.”

"No one can move out, we can't receive any cases from outside the hospital," Dr. Mohammed Salha said.

He added that there was a four-limb drone "fired around the hospital and outdoor areas of the hospital."

"We also heard the tank shooting... maybe 400 or 500 meters (far)."

The IDF told the BBC it "operates in terror targets" but "does not know there is any siege in the hospital itself".

"Even without being attacked or forced to evacuate medical facilities, hostilities and military presence prevent patients and staff from accessing care, and from the hospitals in the supply hospital, this could quickly make them inactive," Dr. Tedros said.

“We’ve seen it too many times – and it must not be allowed to happen again.”

Médecins Sansantières (MSF) also said at least 20 medical facilities in Gaza have been damaged or partially or completely stopped production during Israeli ground operations, air strikes and evacuation orders over the past week.

The charity asked Israeli authorities to stop what is called “intentional suffocation and annihilation of its health care system”.

Israel imposed a blockade on Gaza on March 2 and resumed its military offensive against Hamas two weeks later, ending a two-month ceasefire. It said it wanted to put pressure on Hamas to release its remaining 58 hostages, as many as 23 of whom were believed to be alive.

After several days of intense bombing, the IDF launched an expanded offensive on Sunday, with Prime Minister Benjamin Netanyahu saying ground forces “control all areas of Gaza.” The plan reportedly included the complete removal of civilians to the north and forcibly relocating them to the south.

More than 600 people in Gaza were killed in the past week and 2,000 people were injured in Gaza, according to the Hamas-Ministry of Operations in the region. The United Nations says thousands have been recently displaced.

Netanyahu also said Israel will allow “basic” food in Gaza to prevent famine. However, the United Nations has been unable to collect dozens of trucks since Monday.

Doctors Without Borders said the amount of aid allowed so far is not enough, describing it as a "smoke screen that pretends to be siege is over."

On Tuesday, a representative from the World Health Organization said on the Palestinian Territory that he recently returned from Gaza and witnessed how the health system faced attacks and sharp supply shortages.

"Every time you go into Gaza, you always think that things won't get worse. But things get worse," Dr. Rik Peeperkorn told reporters in Geneva.

He described how Al-Awda hospitals were “injured and overwhelmed” while supply was low. He added that hostilities damaged the facility, access was interrupted and prevented people from seeking health care.

He said Indonesian hospitals were almost inoperable and almost inaccessible, and that most patients left last week after a staff member was killed and one patient was injured, a facility was damaged during the intensification of hostilities.

He added that as of Tuesday, only 15 people, including patients and staff, were still in the hospital and urgently needed food and water.

Mer-C India, the non-governmental organization that built the facility, said the hospital's generator was also hit by an Israeli quad bike on Monday night, causing a fire and a power outage.

A woman in the hospital told the BBC by phone on Wednesday that two of the patients were in a "severe condition".

In the background of the phone, a crash can be heard.

"Five minutes ago, there was a huge shooting around the hospital," she said, adding that she could see the tanks.

The woman also said they still had food in the hospital but were "faced with a water crisis."

The IDF told the BBC that it operates in areas around the hospital and targets "terror infrastructure sites", but it is not aimed at the hospital itself.

In another incident Tuesday, a paramedic said his ambulance was shot by an Israeli drone while transporting staff and food between Al-Awda and Kamal Adwan Hospitals.

Khaled Sadeh said he was accompanying another ambulance when the bullet hit the windshield of two vehicles. No one was injured.

Dr. Salha shared photos of the ambulance and confirmed that Mr. Thad was unable to return to Alvada due to the threat of the Israeli fire.

The BBC provided the IDF with details of the allegations and photos, but it said the report was "unable to confirm".

Hospitals and medical staff are specifically protected by international humanitarian law.

Hospitals can only lose this protection in some cases. These include being used as a base to launch attacks, as a weapon warehouse or a hidden healthy fighter.

The IDF insists that its forces act under international law. In most cases of attacking hospitals, Hamas has said they used them incorrectly - an allegation the organization denied.

Since May 13, in the southern city of Khan Younis, the European hospital - the only facility to provide neurosurgery, cardiac care and cancer treatment in Gaza.

That day, the hospital's courtyard and surrounding areas were attacked by a series of Israeli air strikes by the Israeli Defense Minister, targeting an underground bunker, which Mohammed Sinwar, head of the Hamas military department, hid in hiding. The Hamas Civil Defense Agency, established in Gaza, said the attack killed at least 28 people, but it is not clear whether Singwar died.

The facility has also been in Israel’s designated evacuation zone since Monday, covering almost the entire eastern part of Khan Yunis.

Dr. Tedros said that Nasser, al-amal and al-aqsa hospitals and a field hospital are within 1 km of the area.

Dr Victoria Rose, a British surgeon working at Nasser Hospital, said in a video posted on social media on Wednesday that she was very worried that the facility would be evacuated or cut off by Israeli forces from Al-Aqsa, who was in the central town of Deir Al-Balah.

“If we were cut off from the middle area, there really was no other hospital around us that could deal with Nasser’s evacuation,” she explained.

"We have some amazing field hospitals... but none of them have the ability to do the type of surgery we do here. And none of them have the ICU capacity or the oxygen produced. So even everyone can't cope with the number of patients we have."

“If Nasser is evacuated, we are indeed studying the imminent deaths of hundreds of patients because we will not be able to take them anywhere,” she warned.

Nasser was attacked by an Israeli strike on May 13, killing two people, including a Palestinian journalist, who was treated for injuries suffered during strikes at the tent camp in the complex. According to the WHO, the attack also destroyed 18 beds of the burned unit.

The IDF accused reporters of being a Hamas surgical staff and claimed that the group was using the hospital to "do terrorists."

Another strike on Monday severely damaged Nasser's medical warehouse and destroyed key figures in the supply, according to hospital directors.

Suha Shaath, a pharmacist from Khan Younis, was told by IDF to evacuate and head to the camp in the Al-Mawasi area of ​​the coastal area, and he said in his voice: "Until now I have not left my house because I have not found any place to set up my tent."

"The humanitarian situation is very serious - no water, no food, no fuel. The shells are everywhere."

Israel launched a military campaign in Gaza on October 7, 2023 in response to Hamas' cross-border attacks, in which about 1,200 people were killed and another 251 were taken hostage.

According to the region's Ministry of Health, at least 53,655 people have been killed in Gaza since the Israeli offensive resumed, of which 3,509 have been killed.
