Israel-Gaza-Lebanon updates: Officials say 87 killed in Israeli strikes on Beit Lahia

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.

Oxfam, the nonprofit confederation representing 21 NGOs, called for an independent investigation after four water engineers were killed in a town east of Khan Younis, Gaza on their way to repair water infrastructure.

The engineers worked for an Oxfam partner organization and had coordinated with Israeli authorities to do the work, according to Oxfam.

"Despite prior coordination with Israeli authorities their clearly-marked vehicle was bombed," the organization said.

The Israel Defense Forces has not immediately commented on the attack.
