You fell for Qatari state and Hamas terrorist propaganda. All physical evidence points to a more minor event caused by a failed rocket within Gaza. Only the initial confusion caused the ridiculous claims of 500 dead and the entire hospital up in flames to spread. Do some light reading based on current understanding that isn’t Al Jazeera.

“Israel, the United States, France, the United Kingdom, and Canada said that their intelligence sources indicate the cause of the explosion was a failed rocket launch by the Palestinian Islamic Jihad (PIJ) from within Gaza, while the PIJ has denied any involvement. Hamas said that Israel carried out an airstrike on the hospital. Most experts speaking in the days after the strike agreed with the Israel Defense Forces' analysis that a misfired Palestinian rocket launched at Israel from within Gaza and captured on video was the likely cause of the explosion.”

> Just for the record, there are also claims supported by evidence, that Israel did it.

I've seen no convincing evidence that shows that Israel did it, the creator and damage size is way too small for any Israeli bomb or missile even airburst does not match the features found at the explosion.
