Israeli military strikes have killed at least 17 Palestinians across the Gaza Strip, medics say, as forces stepped up bombardments on central areas and pushed tanks deeper in the north and south of the enclave, reports. Six people were killed in two separate air strikes on a house and near the hospital of Kamal Adwan in Beit Lahiya in the northern Gaza Strip, while four others were killed when an Israeli strike hit a motorcycle in Khan Younis in the south. In Nuseirat, one of the Gaza Strip’s eight historic refugee camps, Israeli planes carried out several air strikes destroying a multi-floor building and hitting roads outside mosques. At least seven people were killed in some of those strikes, health officials said.
