Israeli Prime Minister Benjamin Netanyahu rejected ceasefire proposals because he says Hamas’ call to withdraw all troops from Gaza and end the war is unacceptable.
Netanyahu said accepting such proposals would “leave Hamas intact” and leave the possibility of another attack in the future.
“Giving in to Hamas’s demands would be a terrible defeat for the State of Israel,” he said in a video statement.
Brokered negotiations have been held in Egypt for a pause in fighting in exchange for the release of hostages held by Hamas, but a deal still appears to be some way off.
Hamas said in a statement on Sunday that it is “still interested in reaching a comprehensive and interconnected agreement that ends the aggression, guarantees withdrawal and achieves a serious prisoner exchange agreement.”
The impasse comes after the Egyptian media reported “remarkable progress” in ceasefire talks on Saturday.
The proposal that the mediators had presented to Hamas established a three-stage process for an immediate six-week ceasefire and the partial release of the Israeli hostages, with some form of Israeli withdrawal in return.
More than 34,600 Palestinians have been killed and more than 77,000 injured in From Israel military operation, according to the Gaza Ministry of Health.
Israel has said it remains committed to a ground offensive on the southern city of Rafah, where more than a million people have fled for safety, as it tries to crack down on Hamas.
The UN and others have warned of a catastrophe if it goes ahead.
The war began in October after Hamas killed about 1,200 people, according to Israeli figures, when it launched a surprise attack.
More than 200 were kidnapped and many remain hostage, while others are believed to have died.
