Iran launched many ballistic missiles at Israel on Friday night. Some reports suggest a few missiles hit Tel Aviv, though Israel's military says it stopped most of them. However, some missiles did hit buildings, and 15 civilians were hurt and needed hospital treatment in Tel Aviv. 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 United States has helped shoot down Iranian missiles using ground-based systems. Still, Israel has mostly handled its own defense over the last year with its advanced system. This system can find incoming rockets and fire back if they are heading towards cities or important areas. Israel's air defense has several parts: the Arrow system for long-range missiles, David's Sling for medium-range missiles, and the Iron Dome for short-range rockets. Israel is also developing the Iron Beam, which uses lasers to stop threats.
