73. Placing responsibilty for all acts happening within gaza

on one group is not logical since not all factions are aligned

You can't really put the actions of a rival faction/group as their fault, as stated, Hamas had been working with the IDF to curb rockets being fired which included arresting people who tried or did fire them.

A Salafi official told the newspaper that his group refused to comply with the cease-fire agreement and would continue firing rockets at Israel. The Hamas government arrested Salafi jihadists who claimed responsibility for rocket fire at Israel, the paper reported.

And to be honest, yes i do think that even with the amount of informants and such Hamas has that they are not omnipresent and able to know about every attack planned by rival factions/groups, its not like most groups are stupid enough to leave papers behind with a schedule of when they will fire rockets or whatnot. They can stop a fair number of them but thinking they can stop every one is folly as not even the Commander of IDF's Gaza Division expects that.

“Today Hamas and other actors in Gaza are acting to stop the rocket fire. They don’t always succeed, and where they fail, the IDF acts,” the general said.
