While Sinwar was not killed during a targeted operation, the IDF said that it had for weeks been operating in areas where intelligence indicated his presence.

In short, Israeli forces had narrowed Sinwar's rough location to the southern city of Rafah, and were slowly moving in to get him.

Sinwar had been on the run for more than a year. He had undoubtedly felt the Israeli pressure growing as other Hamas leaders, such as Mohammad Dief and Ismail Haniyeh, were killed, and as Israel destroyed the infrastructure he had used to prosecute the atrocities of 7 October.
