Netanyahu’s office accused Hamas of reneging on an earlier agreement granting Israel a veto over which prisoners convicted of murder would be released in exchange for hostages. This disagreement has delayed the Israeli Cabinet’s approval of the ceasefire deal.
Except the Americans, maybe. To them, that Israel is an honest actor is an (often literal) article of faith.
Edit: Three days on, this story hasn’t exactly held water. I still doubt long-term peace is on Netanyahu’s agenda, because of the whole “lost election = jail” thing, but apparently a ceasefire on the way fits in somehow.
