Dror Or, a 49-year-old held captive in Gaza, has died, the Hostages Families Forum said Friday. Or marks the 38th hostage killed, the forum said.

He was one of about 250 people abducted when Hamas attacked southern Israel on Oct. 7, killing around 1,200 people, mostly civilians. Israel says militants still hold around 100 hostages and the remains of more than 30 others.

Dozens of people demonstrated Thursday night outside Israel’s military headquarters in Tel Aviv, demanding a deal to release the hostages. Meanwhile, Hamas said it would send a delegation to Cairo as soon as possible to keep working on cease-fire talks. A leaked truce proposal hints at compromises by both sides after months of talks languishing in a stalemate.

Across the United States, tent encampments and demonstrations against the Israel-Hamas war have spread across university campuses. More than 2,000 protesters have been arrested over the past two weeks as students rally against the war’s death toll and call for universities to separate themselves from any companies that are advancing Israel’s military efforts in Gaza.
