Iran and Israel have attacked each other. Israel attacked Iran's nuclear program and army. Then, Iran sent missiles and drones back. Three people died and many were hurt in Iran. Iran said Israel used planes and hidden drones. This killed 78 people and hurt over 320. Israel said they attacked to stop Iran from making nuclear weapons. But some people think Iran is not making them now. Iran's attack caused fear and damage in Israel. Because of these attacks, it is not clear if the U.S. and Iran will continue talking about nuclear issues. Iran said the talks are now "meaningless" after Israel's attacks. But they have not decided to stop the talks completely. People around the world are worried this could start a bigger war. They are asking both sides to calm down.
