Israeli strikes across the Gaza Strip have killed at least 30 Palestinians since Monday night, Palestinian media and medics said, as the Israeli army tightened its siege on northern areas of the enclave, reports. An airstrike damaged two houses in the town of Beit Lahiya in northern Gaza, where the army has carried out new operations since October 5, and killed at least 20 people late on Monday, news agency Wafa and Hamas media said. The Gaza health ministry did not immediately confirm the toll. Four other people were killed in the central Gazan town of Al-Zawayda around midnight on Monday, medics said. Palestinian health officials said six people had also been killed in two separate Israeli airstrikes in Gaza City and Deir Al-Balah in the central area of the narrow enclave. The Israeli military said, without giving details, that its forces had “eliminated terrorists” in the central Gaza Strip and Jabalia area. Israeli troops had also located weapons and explosives over the past day in the southern Rafah area, where “terrorist infrastructure sites” had been eliminated, it said. Palestinians said the new attacks and Israeli orders for people to evacuate were aimed at emptying two northern Gaza towns and a refugee camp to create buffer zones.
