Israeli tanks pushed back into parts of the northern Gaza Strip on Tuesday that they had left weeks ago, while warplanes conducted air strikes on Rafah, the Palestinians' last refuge in the south of the territory, killing and wounding several people, medics and residents said.

Residents reported an internet outage in the areas of Beit Hanoun and Jabalia in northern Gaza. Tanks advanced into Beit Hanoun and surrounded some schools where displaced families have taken refuge, according to the residents and media outlets of the militant Palestinian group Hamas.

"Occupation soldiers ordered all families inside the schools and the nearby houses where the tanks had advanced to evacuate. The soldiers detained many men," one resident of northern Gaza said via a chat app.
