Israeli military strikes have killed at least 30 Palestinians overnight in the Gaza Strip, most of them in the Nuseirat camp at the centre of the enclave, medics said after some tanks pulled back from an area they had raided, according to . Medics said they had recovered 19 bodies of Palestinians killed in the northern areas of Nuseirat, one of the enclave’s eight long-standing refugee camps. Some tanks remained active in the western area of the camp and the Palestinian Civil Emergency Service said teams were unable to respond to distress calls from residents trapped inside their houses. The rest were killed in the northern and southern areas of the Gaza Strip, medics added.
