On Friday night, Iran fired missiles at Israel. Some people think a few of these missiles hit Tel Aviv. Israel's army said they stopped most of the missiles, but some still hit buildings. Hospitals in Tel Aviv are helping 15 people who were hurt. This attack is a big test for Israel's air defense system. This system has been stopping rockets from different countries since the war began on October 7, 2023. The US is helping to shoot down Iran's missiles. But Israel has mostly defended itself for the past year with its good system. This system can see rockets coming and stop them if they are going towards cities or or important areas. Israel's air defense uses different systems: Arrow for long-distance missiles, David's Sling for middle-distance missiles, and Iron Dome for short-distance rockets. Israel is also making a new system called Iron Beam that uses lasers to stop threats.
