Hamas stood by its demand on Tuesday that Israel fully end its assault on Gaza under any deal to release hostages and said US President-elect Donald Trump was rash to say there would be "hell to pay" unless they go free by his Jan. 20 inauguration.
Officials from the Islamist terror group and Israel have been holding talks with Qatari and Egyptian mediators in the most intensive effort for months to reach a ceasefire in Gaza.
The outgoing US administration has called for a final push for a deal before Joe Biden leaves office, and many in the region now view Trump's inauguration as an unofficial deadline.
But with the clock ticking, both sides accuse the other of blocking a deal by adhering to conditions that torpedoed all previous peace efforts for more than a year.
Hamas says it will free its remaining hostages only if Israel agrees to end the war and withdraw all its troops from Gaza. Israel says it will not end the war until Hamas is dismantled and all hostages are free.
