An investigation into the missile strike on a building in Haifa has revealed that it was a standard Iranian missile weighing several hundred kilograms.
The investigation, conducted by the Israeli Air Force and the IDF, determined that the ballistic missile launched from Iran broke apart mid-air, causing the interceptors fired at it to miss.
The penetrating body, which contained several hundred kilograms of explosives, struck the building and caused its collapse. The warhead did not detonate, and the damage at the site resulted from the structural collapse rather than from an explosion or blast wave.
According to assessments by rescue officials at the scene, had the warhead exploded, far more extensive damage would have been caused to surrounding buildings, and there would have been a significant blast radius.
In practice, the unexploded missile caused several floors of the building to collapse, but the overall blast impact was relatively limited compared to other impact sites. The building contained a shelter, and most residents were inside it and emerged unharmed.
Four people were unaccounted for following the missile strike, and it is believed that none of the four were inside the building's shelter.
Early on Monday morning, rescue forces recovered the bodies of two of the four from under the rubble of the building.
Rescue forces and the Home Front Command continue to search for two additional missing persons. The four missing individuals are an elderly couple, their son (approximately 40 years old), and their caregiver.
