Human rights activists, relatives and ex-detainees allege the Israeli military has rounded up hundreds of Palestinians in northern Gaza, forced men to strip to their underwear and subjected them to hunger and cold.
Experts say the roundups have laid bare an emerging tactic in Israel's ground offensive in Gaza, nearly 10 weeks after the deadly October 7th attack on southern Israel by Hamas.
A former adviser to Prime Minister Benjamin Netanyahu says the roundups are crucial for the next stage of the war, where Israel cleans areas from all the remnants of Hamas.
The Israeli military says detainees were treated according to protocol and given enough food and water.
