IDF: An analysis of IDF operational systems indicates that a barrage of rockets was fired by terrorists in Gaza, passing in close proximity to the Al Ahli hospital in Gaza at the time it was hit.
Intelligence from multiple sources we have in our hands indicates that Islamic Jihad is responsible for the failed rocket launch which hit the hospital in Gaza.
Update
Videos published by various sources, alleged to show the Islamic Jihad rocket that hit the hospital:

None of these videos line up with each other, so at least two of them must be irrelevant if not all three.
Meanwhile, the closest video shows an incoming whistle: https://twitter.com/i/status/1714366113818038412
