As families in Israel and Gaza mourn their losses, Israel says it defeated Hamas in a key city, and that its military's focus has shifted to Gaza's southern border.

The effects of the war are being felt throughout Israel and Gaza as Israel's military campaign intensifies. The United Nations reports that 90% of the people in Gaza regularly go a whole day without food and other basic necessities like clean water, fuel, medicine and medical supplies.

President Biden, meanwhile, issued an executive order that targets Israeli settlers in the West Bank who have been accused of attacking Palestinians.

Here is a selection of the photos from this past week:
