TEL AVIV, Israel (AP) — Israeli Prime Minister Benjamin Netanyahu says a “tragic mishap” was made in an Israeli strike in the southern Gaza city of Rafah that set fire to a tent camp housing displaced Palestinians. Local officials say at least 45 people were killed in Sunday’s strike. It only added to the surging international criticism Israel has faced over its war with Hamas. Netanyahu did not elaborate on the error. Israel’s military initially said it had carried out a precise airstrike on a Hamas compound, killing two senior militants. As details of the strike and fire emerged, the military said it had opened an investigation into the deaths of civilians.
