Hezbollah fired several missiles from Lebanon towards Israel on Sunday, two days after the U.S. and Israel launched strikes on Iran , the IDF said. Why it matters: Hezbollah's attack expands the current conflict to another country in the region and threatens to seriously destabilize Lebanon. While seriously degraded by almost daily Israeli strikes over the past year, Hezbollah is still Iran's strongest and most important and strongest proxy in the region. What they're saying: "Following the sirens that sounded in several areas in northern Israel, a projectile that crossed from Lebanon into Israeli territory was intercepted by the Israeli Air Force, and several projectiles fell in open areas in accordance with standard protocols," the IDF said in a statement. "No injuries or damages were reported." Hezbollah didn't claim responsibility for the attack. Between the lines: Israel warned both in private and in public in recent days that if Hezbollah were to open a new front on the Israeli-Lebanese border during a war with Iran, it would retaliate harshly.
