Sources close to the talks have said that US and Arab mediators are working round-the-clock to hammer out a ceasefire deal between Israel and Hamas even as Gaza Strip medics said Israeli strikes have killed 41 Palestinians, reports. Mediators had managed to narrow some gaps on previous sticking points but differences remained, the sources said. In Gaza, medics said at least 13 Palestinians were killed overnight in separate Israeli airstrikes, including on two houses in Gaza City and a central camp. Medics said an Israeli airstrike killed nine people near Beach refugee camp in Gaza City, while another killed four others at a housing project near Beit Lahiya in the north. There was no Israeli comment. Later, airstrikes killed at least 15 Palestinians in two shelters housing displaced families in eastern Gaza City’s suburb of Tuffah, medics said, bringing today’s death toll to 41.
