An explosion happened at a Jewish school. It was early Saturday in Amsterdam. This made Jewish people feel very worried. The Mayor said it was a bad attack. She called it a cowardly act.
The school had only a little damage. Police think someone did it on purpose. The explosion was in a rich part of the city. Help came fast.
This is part of a bad trend. Jewish places in Europe were attacked. A synagogue in Rotterdam had a fire. Another explosion was in Belgium. These make Jewish people afraid. They worry about hate.
Mayor Femke Halsema said Jewish people face more hate. She said this is not okay. The city will look into this. Global problems may make bad people bolder.
The attacks show a pattern. They make Jewish people sad. Security at Jewish places was already higher. This new explosion means more security checks.
Police are looking for who did it. They want to know why. The attack is a problem for the Jewish community. People around the world are watching. Many people help Jewish people in Amsterdam.
