World Health Organization Director-General Tedros Adhanom Ghebreyesus reiterated calls for the protection of the few hospitals still operating inside Gaza on Saturday, following reports of fresh Israeli strikes on two health care facilities in the north of the strip.

"Hostilities in the vicinity of hospitals can quickly make them non-functional by compromising access," Ghebreyesus wrote on X. "We cannot request any more loudly: health care must be protected."

Ghebreyesus' latest appeal followed reported Israeli attacks on the Indonesian Hospital and Al-Awda Hospital in northern Gaza.

Both are in the Jabalia area in the north of the strip, which is the focus of a fresh Israeli offensive and a sweeping evacuation order for residents.

"We call for sustained and safe access to reach all patients and health workers in need," Ghebreyesus wrote. "We call for an immediate ceasefire!"

"It is vital that Kamal Adwan and Al-Awda hospitals remain operational," Ghebreyesus said.

Gaza's 36 hospitals and nine field hospitals have been badly affected by more than a year of war.

ABC News analysis found that as of Sept. 24, only four field hospitals were still functional, all in the central or southern areas of the strip. Twenty-two hospitals were partially functioning, with the remaining 19 non-functioning.

Israeli Foreign Minister Israel Katz on Sunday dismissed Iran's denial of involvement in a drone attack that targeted Israeli Prime Minister Benjamin Netanyahu's residence in the northwestern coastal town of Caesarea on Saturday.

Iran's mission to the United Nations attributed the attack to its Lebanese ally Hezbollah, per a statement to the official IRNA news agency.

One drone impacted a building close to Netanyahu's residence. Two others were intercepted. A spokesperson for his office said neither the prime minister nor his wife were present at the time of the attack.

"The primary proxy, the tentacle Iran created, funded, armed, trained, and now controls in all its operations, is suddenly portrayed as an independent entity," Katz wrote in a post to X on Sunday.

"Your lies and false pretenses won't help you -- you are responsible," the foreign minister added, referring to Iran.

Netanyahu also blamed Tehran. "The proxies of Iran who today tried to assassinate me and my wife made a bitter mistake," the prime minister said shortly after the incident.

The Israel Defense Forces wrote on X early Sunday that its warplanes "attacked about 175 terrorist targets in Gaza and Lebanon" over the previous 24 hours.

Among the facilities targeted were what the IDF called "weapons warehouses, launch shafts, military buildings and terror infrastructures" it said belonged to Hamas and Hezbollah.

The director of the Kamal Adwan Hospital in Beit Lahia, in North Gaza said in a statement that the facility is receiving so many patients that "many of the injured have died due to the inability" to treat them.

Dr. Hossam Abu Safia said the hospital has been triaging the worst cases due to lack of staff and supplies.

He said many people are still missing with crews unable to reach them, and that there is "heavy bombing and gunfire" around the hospital.
