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.

The Israel Defense Forces said Friday morning that its ground troops had begun operating in the Shejaiya area of the northern Gaza Strip.

Israel resumed its military offensive in Gaza in March, blaming Hamas for rejecting a new US proposal to extend the ceasefire and free the remaining hostages. Since then, the Israeli military has launched waves of airstrikes on the besieged territory, killing hundreds of Palestinians and forcing many more to evacuate.
