Israeli military strikes across Gaza have killed at least 65 Palestinians overnight, including in a school sheltering displaced families, medics said, as Israeli tanks advanced in areas of Khan Younis in the south of the enclave. Israeli tanks carried out a raid on several areas in eastern and central Khan Younis in southern Gaza, before partially retreating, leaving at least 40 people killed and dozens wounded, according to the official Voice of Palestine radio. In Gaza City, at least 22 Palestinians were killed, the medics said.
