"Neither the fascist enemy and its arrogant leadership... nor its supporters... can take their captives alive without an exchange and negotiation and meeting the demands of the resistance," Abu Obeida, spokesman for Hamas's armed wing, said in a televised broadcast, referring to the release of Palestinian prisoners held by Israel.
A one-week truce in the war that collapsed on December 1 saw 105 captives held by the group freed, including 80 Israelis released in exchange for 240 Palestinian prisoners.
Israel on Saturday said 137 captives remained in the Palestinian territory.
Mediator Qatar said on Sunday that efforts to secure a new truce and release more captives were ongoing but warned that the relentless Israeli bombardment was "narrowing the window" for a successful outcome.
Obeida said the group would continue to fight Israeli occupation forces.
"We have no choice but to fight this barbaric occupier in every neighbourhood, street and alley," he said.
"The enemy's holocaust aims to break the strength of our resistance... but we are fighting on our land in a holy battle."
The war in Gaza was triggered after Al-Aqsa Flood Operation on October 7 that killed 1,200 people, according to Israeli officials.
Since then, Israel launched an air, land and sea assault on the Gaza Strip, in which at least 17,700 people, most of them children and women, have been killed, according to the latest figures from the Palestinian health ministry.
