Iran fires overnight missile wave at Israel — IDF issues shelter alert, sirens across northern Israel

Iran launched a missile wave at Israel shortly before midnight UTC on Day 18 (Guardian, 23:46 UTC). The IDF issued an urgent shelter alert stating missiles were launched from Iran and directed the public to shelters. Sirens sounded across northern Israel. Israeli rescue services (Haaretz) initially reported no injuries or damage from the attack. The salvo is the first confirmed barrage of Day 18 and follows five distinct Day 17 salvos including a cluster munitions strike and repeated Qatar/Al Udeid barrages. Iran has now fired salvos at Israel on every day of the conflict. Despite IDF assessment that 70%+ of Iranian missile launchers are inoperable, Iran's residual inventory continues to generate overnight fire. IDF evening strikes across Iran on Day 17 night did not prevent this Day 18 salvo.
