DEIR AL-BALAH, Gaza Strip (AP) — Israelis again poured into the streets for another large protest over the government's failure to secure the return of remaining hostages in Gaza , while hospital and local authorities said Israeli air raids in the territory killed more than a dozen people overnight into Saturday. Health workers wrapped up the second phase of an urgent polio vaccination campaign designed to prevent a large-scale outbreak. The drive, launched after the first polio case in the Palestinian enclave in 25 years, aims to vaccinate 640,000 children during a war that has destroyed Gaza's health care system and much of its infrastructure.

The third phase of vaccinations will be in the north. Israel kept up its military offensive. In central Gaza’s urban refugee camp of Nuseirat, Al-Awda Hospital said it received the bodies of nine people killed in two air raids.

One hit a residential building, killing four people and wounding at least 10, while five people were killed in a strike on a house in western Nuseirat. Separately, Al-Aqsa Martyrs Hospital, central Gaza’s main hospital, said a woman and her two children were killed in a strike on a house in the nearby urban refugee camp of Bureij. In northern Gaza, an airstrike on a school-turned-shelter for displaced people in the town of Jabaliya killed at least four people and wounded about two dozen others, according to Gaza’s Civil Defense authority, which operates under the territory’s Hamas-run government.
