The Israeli Air Force is investigating the failure to shoot down the Iranian ballistic missile that struck Tel Aviv this morning. According to the military, the Iranian missile carried a conventional warhead, not a cluster bomb. The impact lightly injured four people and caused extensive damage to several buildings. The IDF says several attempts to intercept the missile were made, but air defenses failed to knock the projectile down. The missile used in the attack has been intercepted before, and is not considered a new threat, the IDF adds.
