At least 27 Palestinians have been killed in an Israeli air strike on a school in northern Gaza that was serving as a shelter for displaced families, the Hamas-run health ministry says.Dozens more were wounded when the Dar al-Arqam school in the north-eastern Tuffah district of Gaza City was hit,

The Israeli military said it was looking into reports about the deaths at a school-turned-shelter, which came as Israel was intensifying its offensive in Gaza to pressure Hamas to release hostages.

DEIR AL BALAH, Gaza Strip (AP) — An Israeli airstrike on Thursday killed at least 27 Palestinians sheltering at a school in northern Gaza and wounded 70 more, said Health Ministry spokesman Zaher al-Wahidi, as Israeli forces have expanded their strikes and evacuation orders across the war-torn territory in recent days.

Israeli Prime Minister Benjamin Netanyahu said Israel’s military is “switching gears” in Gaza, dividing and seizing more parts of the strip, a move experts say could mean Israel establishing deeper, more long-term control over the territory.

In pressing forward with its assault on the territory, Israel hopes to squeeze Hamas into releasing the remaining hostages. But other objectives have emerged.
