War returns to Gaza after Israel and Hamas cease-fire ends

War has returned to Gaza after a week-long cease-fire. The pause saw Hamas release more than 100 hostages, Israel free more than 240 Palestinians and hundreds of aid trucks allowed into Gaza. Negotiators are working to reinstate the temporary truce that ended Friday, but the Gaza health authority controlled by Hamas said more than 175 Palestinians have already been killed.
