DEIR AL-BALAH: The Israeli military has rounded up hundreds of Palestinians across the northern Gaza Strip, separating families and forcing men to strip to their underwear before trucking some to a detention camp on the beach, where they spent hours, in some cases days, subjected to hunger and cold, according to human rights activists, distraught relatives and released detainees themselves.
Palestinians detained in the shattered town of Beit Lahiya, the urban refugee camp of Jabaliya, and neighborhoods of Gaza City said they were bound, blindfolded, and bundled into the backs of trucks.
Some said they were taken to the camp at an undisclosed location, nearly naked and with little water.
“We were treated like cattle. They even wrote numbers on our hands,” said Ibrahim Lubbad, a 30-year-old computer engineer arrested in Beit Lahiya on Dec. 7 with a dozen other family members and held overnight.
“We could feel their hatred.”
The roundups have laid bare an emerging tactic in Israel’s ground offensive in Gaza, experts say, as the military seeks to solidify control in evacuated areas in the north and collect intelligence about Hamas operations nearly 10 weeks after the group’s deadly Oct. 7 attack on southern Israel.

In response to questions about alleged mistreatment, the Israeli military said that detainees were “treated according to protocol” and were given enough food and water.
The army spokesman, Rear Adm. Daniel Hagari, claimed that the men are questioned and then told to dress and that in cases where this did not happen, the military would ensure it does not occur again.
Those believed to have ties to Hamas are taken away for further interrogation, and dozens of Hamas members have been arrested so far, he claimed.
Photos and videos showing Palestinian men kneeling in the streets, heads bowed, and hands bound behind their backs sparked outrage after spreading on social media.
To Palestinians, it is a stinging indignity. Among those rounded up were boys as young as 12 and men as old as 70, and they included civilians who lived ordinary lives before the war, according to interviews with 15 families of detainees.
“My only crime is not having enough money to flee to the south,” said Abu Adnan Al-Kahlout, an unemployed 45-year-old with diabetes and high blood pressure in Beit Lahiya.
He was detained Dec. 8 and released after several hours when soldiers saw he was too faint and nauseated to be interrogated.
Israeli forces have detained at least 900 Palestinians in northern Gaza, estimated Ramy Abdu, founder of the Geneva-based Euro-Med Human Rights Monitor, which has worked to document the arrests.
Based on testimony it collected, the group presumes Israel is holding most detainees from Gaza at the Zikim military base just north of the enclave.
Palestinians cowered with their families for days as Israel poured heavy machine-gun fire into Beit Lahiya and Jabaliya, the firefights with Hamas militants stranding families in their homes
without electricity, running water, fuel or communications, and internet service.
“There are corpses all over the place, left out for three, four weeks because no one can reach them to bury them before the dogs eat them,” said Raji Sourani, a lawyer with the Palestinian Center for Human Rights in Gaza.
He said he saw dozens of dead bodies as he made his way from Gaza City to the southern border with Egypt last week.
Palestinians recounted soldiers going door to door with dogs, using loudspeakers to call on families to come outside.
Women and children are often told to walk away to find shelter.
Some released detainees described enduring humiliating stretches of near-nudity as Israeli troops took the photos that later went viral.
Some guessed they were driven several kilometers before being dumped in cold sand.
Released detainees said they were exposed to the chill of night and repeatedly questioned about Hamas activities that most could not answer.
Soldiers kicked sand in their faces and beat those who spoke out of turn.
Several Palestinians held for 24 hours or less said they had no food and were forced to share three 1.5-liter bottles with some 300 fellow detainees.
Darwish Al-Ghabrawi, a 58-year-old principal at a UN school, fainted from dehydration.
Mahmoud Al-Madhoun, a 33-year-old shopkeeper, said the only moment that gave him hope was when soldiers released his son, realizing he was just 12.
Returning home brought its horrors. Israeli soldiers dropped detainees off after midnight without their clothes, phones, or IDs near what appeared to be Gaza’s northern border with Israel, those released said, ordering them to walk through a landscape of destruction, tanks stationed along the road and snipers perched on roofs.
“It was a death sentence,” said Hassan Abu Shadkh, whose brothers, 43-year-old Ramadan and 18-year-old Bashar, and his 38-year-old cousin, Naseem Abu Shadkh, walked shoeless over jagged mounds of debris until their feet bled.
Naseem, a farmer in Beit Lahiya, was shot and killed by an Israeli sniper as they made their way to a UN school in Beit Lahiya, Abu Shadkh said.
His brothers were forced to leave their cousin’s body in the middle of the road.
Israeli officials say they have reason to be suspicious of Palestinians remaining in northern Gaza, given that places like Jabaliya and Shijaiyah, in eastern Gaza City, are well-known Hamas bastions.
Human rights groups say mass arrests should be investigated.
“Civilians must only be arrested for necessary and imperative reasons for security. It’s a very high threshold,” said Human Rights Watch’s regional director Omar Shakir.
