On Thursday, Netanyahu said, "The person who committed the most terrible massacre in the history of our nation since the Holocaust, the mass murderer who killed thousands of Israelis and kidnapped hundreds of our citizens, was eliminated today by our heroic soldiers."

Sinwar took over Hamas after former leader Ismail Haniyeh was assassinated in July during a visit to Iran. The Israeli military said Sinwar and two other militants were killed during an operation in Rafah, in southern Gaza. It added that he had run into a building that was hit by a tank shell.
