Hamas, the group which controls the Gaza Strip, has ruled out any more hostage releases until Israel agrees to a "full cessation of aggression".
Fighting continues in Gaza, with Israel bombarding the north and south of the territory and Hamas firing rockets at Tel Aviv.
Among the Palestinians reported killed were the director of the police station in the southern city of Khan Younis and a daughter of the head of the Gaza health ministry.
The week-long truce this month brought an increased flow of aid into Gaza, where the UN has warned that the population is at risk of famine if the war between Israel and Hamas continues.
In a statement, Hamas said: "There is a Palestinian national decision that there should be no talk about prisoners or exchange deals except after a full cessation of aggression."
Early on Friday, the territory's Hamas-run health ministry put the overall death toll there since 7 October at 20,057, including at least 8,000 children and 6,200 women.
