Rescuers in Gaza said Saturday that Israeli strikes across the Palestinian territory killed more than 30 people, as mediators launched a new ceasefire push to end the 15-month-old war.At least 17 of those who died were killed in airstrikes on two houses in Gaza City, the first of which destroyed the home of the Al-Ghoula family in the early hours, medics and residents said.Another strike on a house in Gaza City killed five people later Saturday, the Palestinian Civil Emergency Service said, adding that at least 10 others were feared trapped under the rubble.At least six other Palestinians were killed in Israeli strikes in Jabalia in the north and near the central town of Deir Al-Balah, medics said.Saturday's deaths brought the toll to 70 since Friday, Palestinian health officials said.Israeli Defence Minister Israel Katz confirmed Saturday that indirect negotiations with Palestinian resistance movement Hamas have resumed in Qatar.The minister told relatives of one of the hostages, woman soldier Liri Albag, that "efforts are under way to free the hostages, notably the Israeli delegation which left Friday for negotiations in Qatar", his office said.Renewed push is under way to reach a ceasefire in the war between Israel and Palestinian resistance movement Hamas and return Israeli hostages before US President-elect Donald Trump takes office on Jan. 20.Israeli mediators were dispatched to resume talks in Doha brokered by Qatari and Egyptian mediators, and US President Joe Biden's administration, which is helping broker the talks, urged Hamas and Israel on Friday to agree to a deal.Hamas said it was committed to reaching an agreement as soon as possible, but it was unclear how close the two sides were.Israel's military campaign has leveled swathes of the enclave, driving most people from their homes, and has killed 45,717 Palestinians, according to the Gaza health ministry.AFP adds from Washington: The administration of US President Joe Biden has notified Congress of a planned $8bn arms sale to Israel, a source familiar with the plan said Saturday.The State Department "has informally notified Congress of an $8bn proposed sale of munitions to support Israel's long-term security by resupplying stocks of critical munitions and air defence capabilities," the official said, speaking on condition of anonymity.The weapons package includes medium-range air-to-air missiles to defend against aerial threats; Hellfire AGM-114 missiles; 155mm projectile artillery shells for long-range targeting; and 500-pound warheads, the official said.The Biden administration has provided Israel with billions in arms aid since Israeli forces launched a massive attack on Gaza on October 7.But against the backdrop of a rising Palestinian death toll and the increasingly dire conditions facing civilians, the US support has become a sensitive political issue.Many Arab and Muslim Americans, joined by some progressives, vowed not to vote for Biden in the November presidential election unless he halted the weapons aid to Israel. Students on dozens of US campuses protested the aid.Donald Trump, an outspoken supporter of Israel, said during the US presidential campaign that if elected he would quickly end the Gaza war, although he did not explain how.
