Israel's Prime Minister Benjamin Netanyahu has rejected Hamas's proposed ceasefire terms - saying "total victory" in Gaza is possible within months.
He was speaking after Hamas laid out a series of demands in response to an Israel-backed ceasefire proposal.
He said negotiations with the group were "not going anywhere" and described their terms as "bizarre".
Talks between negotiators are continuing.
"There is no other solution but a complete and final victory," Mr Netanyahu told a press conference on Wednesday.
"If Hamas will survive in Gaza, it's only a question of time until the next massacre."
Reuters news agency quoted a senior Hamas official as saying Mr Netanyahu's remarks on the ceasefire proposal show he intends to pursue the conflict in the region.
Hamas is prepared to deal with all options, the official was quoted as saying.
An Egyptian official source told the BBC that a new round of negotiations is expected to start tomorrow in Cairo, sponsored by Egypt and Qatar.
Egypt calls on all parties to show the necessary flexibility to reach a calm agreement, the source said.
