What is Gaza?
Gaza is a small, densely populated Palestinian coastal strip bordering Israel and Egypt, where years of war have left most people displaced and many living in tents.
What are the Israel Defense Forces?
The Israel Defense Forces are Israel’s national military, the force that carries out Israeli strikes in Gaza.
What was the October ceasefire?
It was an agreement reached in October meant to pause the fighting in Gaza; strikes have nonetheless continued.
Why does this matter?
Flooded shelters and hits on medical facilities leave displaced families with even less protection and care in an already severe humanitarian crisis.
