TEL AVIV, Israel—Prime Minister Benjamin Netanyahu said Monday that a “tragic mistake” was made in an Israeli strike in the southern Gaza city of Rafah that set fire to a camp housing displaced Palestinians and, according to local officials, killed at least 45 people.
Mr. 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 terrorists. As details of the strike and fire emerged, the military said it had opened an investigation into the deaths of civilians.
