Officials and aid groups warn of a worsening humanitarian crisis in Israel and Gaza, where escalating violence has already killed thousands of people and wounded and displaced many others.
Hamas militants launched a surprise attack on Israel on Saturday, firing rockets from Gaza and infiltrating the country by paraglider, motorbike and boat. They gunned down Israelis in multiple locations, including residential communities and a techno music festival, in the deadliest day for Jewish civilians since the Holocaust.
