On Friday night, Iran launched missiles at Israel, and some are believed to have hit Tel Aviv. The Israeli military says they stopped most of the missiles, but some still hit buildings. Hospitals in Tel Aviv are treating 15 civilians who were injured in the attack. This attack is a big challenge for Israel's air defense system, which has been stopping rockets from different countries since the war started on October 7, 2023. The US has helped shoot down Iranian missiles using ground-based defense systems. However, Israel has mostly handled its own defense over the past year with its advanced system. This system can find incoming rockets and activate when they are heading towards populated or important areas. Israel's air defense has different parts: the Arrow system stops long-range missiles, David's Sling stops medium-range missiles, and the Iron Dome stops short-range rockets. Israel is also developing the Iron Beam, which uses laser technology to stop threats.
