Hamas on Monday accused Prime Minister Benjamin Netanyahu of putting hurdles in front of ceasefire negotiations, with talks aimed at reaching a truce-hostage release deal set to renew this week.

The statement came a day after Netanyahu appeared to take mediators as well as some Israeli officials by surprise when he issued a list of four non-negotiable demands ahead of the resumption of talks.

The list included a guarantee that Israel would be allowed to return to fighting in Gaza “until its war aims are achieved,” a key sticking point during months of indirect negotiations. The statement from Netanyahu’s office was met with anger by anonymous Israeli security officials and mediators, who, not for the first time, accused the prime minister of trying to sabotage the deal in order to ensure the survival of his imperiled government.

A statement on the Hamas Telegram channel Monday evening said that Haniyeh had told mediators during a call that he held Netanyahu and the Israeli army fully responsible for the potential collapse of negotiations, and that an escalation in fighting could push things back to “point zero.”
