Israel-Gaza-Lebanon live updates: Israeli airstrike kills water engineers, NGO says

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.

Israel Prime Minister Benjamin Netanyahu called the drone attack that targeted his house an "attempt to assassinate me and my wife," in a statement Saturday.

"The attempt by Iran’s proxy Hezbollah to assassinate me and my wife today was a grave mistake. This will not deter me or the State of Israel from continuing our just war against our enemies in order to secure our future," Netanyahu said.

"Anyone who tries to harm Israel’s citizens will pay a heavy price. We will continue to eliminate the terrorists and those who dispatch them," Netanyahu said.

Hezbollah has not commented on the attack.

Israel said "hundreds of civilians" have decided to leave Jabalia, in Gaza, through IDF-organized routes, but one woman told a local journalist that she and others were forced to leave.

Israel released a video showing multiple IDF tanks and military vehicles stationed outside schools next to the Indonesian hospitals where people were sheltering.

A video shows Palestinians lined up in front of the vehicles, with some moving to sit in a group next to the vehicles -- including at least two in wheelchairs -- and others moving away from the schools and down the road.

Israel said they "arrested a number of terrorists" and "detained them for investigation," although it's unclear if all the people in the seated group are under arrest. Photos released by the IDF show people around the schools with their hands up, holding ID papers, although it's unclear if they were arrested.

A woman, speaking to a local journalist farther south in Northern Gaza, said Israeli forces forcibly expelled them from the school. She said there were strikes and drones around the school overnight.

Israeli forces "took us, they first took all the males over 16, god knows where they took them, then they took us the women and made us walk a long distance with no food, no water," she said.
