Soldiers from Israel attacked a place in Gaza to try and capture a mean leader from Hamas, a group that sometimes fights with Israel.
The soldiers wanted to get Mohammad Sinwar, a very important person in Hamas, who they say is very bad.
Big clouds of smoke appeared near a hospital after the attack, making people worry about the hospital.
This is all part of a big fight between Israel and Hamas that has lasted a long time, and it is making many people very sad.
