Israel attacked Iran's capital, aiming at its nuclear program and killing at least two important military leaders. This was the biggest attack Iran has experienced since its war with Iraq in the 1980s. Israeli leaders stated they had to attack first to prevent Iran's nuclear program from becoming a danger. In response, Iran sent drones, and its leader promised to punish Israel strongly. Israeli planes hit about 100 targets, including Iran's main nuclear facility. After the attack, the airspace was closed in Israel, Iran, Iraq, and Jordan, and oil prices increased significantly. Israel's Defense Minister warned that Iran would likely retaliate immediately.
