When grown-ups have disagreements, sometimes they fight with each other. When this happens, people can get hurt or even worse, they can die. This is what happened when Palestine was at war with Israel. Many people who lived in Palestine were hurt or killed. These people are called Palestinian casualties of war.
When people die or get hurt in a war, it is called a casualty. In this case, Palestine was fighting with Israel, and many people who lived in Palestine were hurt or killed during the fighting. This is very sad and makes many people around the world feel upset.
Sometimes, when people are hurt or killed during a war, they are not just soldiers but they are normal people who were just trying to live their lives. This is what happened to many Palestinians. They were just trying to go about their daily lives when the fighting broke out, and they got hurt or killed because of it.
It is important to remember that wars and fighting can have terrible consequences for many people, including innocent civilians who have nothing to do with the conflict. That's why it's important to work towards peace and find ways to resolve conflicts without violence.
