I believe they where referring to this:

“Hamas has reneged on parts of the agreement reached with the mediators and Israel in an effort to extort last-minute concessions,” [Netanyahu’s] Office said. The statement said that the cabinet will not convene until Hamas has accepted all the terms of the agreement.”

Israel bombing Gaza after the ceasefire deal. At least 81 people were killed and at least 188 people were injured. I don't know if those 81 deaths includes the 45 deaths Israel killed from another bombing shortly after the ceasefire was announced.

On Israel's side, Israel claimed Hamas has reneged on parts of the agreement. I can't find any specifics.
