Israeli airstrikes in expanded offensive kill at least 90 and destroy 2 homes, officials say

More than 90 Palestinians, including dozens from an extended family, were killed in Israeli airstrikes on two homes, rescuers and hospital officials said Saturday, a day after the U.N. chief warned again that nowhere is safe in Gaza and that Israel's ongoing offensive is creating "massive obstacles" to the distribution of humanitarian aid.

Also Saturday, the Israeli military said troops arrested hundreds of alleged militants in Gaza over the past week and transferred more than 200 of them to Israel for further interrogation, providing rare details on a controversial policy of mass roundups of Palestinian men. The army said more than 700 people with alleged ties to the militant groups Hamas and Islamic Jihad have so far been sent to Israeli lockups.

Israel declared war after Hamas gunmen stormed across the border on Oct. 7, killing some 1,200 people and taking some 240 hostages. More than 20,000 Palestinians have been killed in Israel's war to destroy Hamas and more than 53,000 have been wounded, according to health officials in Gaza, a besieged territory ruled by the Islamic militant group for the past 16 years.
