Israel launched attacks on Iran's air-defense systems around critical energy sites, including oil and petrochemical refineries, a gas field, and a major port in southern Iran. The destruction of these systems has raised concerns in Iran about the vulnerability of energy and economic hubs to future attacks. Iran's military reported four soldiers killed in the attacks, and Iranian media expects the casualty numbers to rise. Israel initially planned to strike Iran's energy industry and nuclear project but decided to target the air defenses instead, according to Israeli officials. Iran's Supreme National Security Council held an emergency meeting to discuss a response.
