Iranian Supreme Leader Ali Khamenei said Saturday that the killing of Hamas chief Yahya Sinwar will not slow the resistance war its proxy groups are waging against Israel.

The Israel Defense Forces confirmed Thursday that Israeli forces killed Sinwar, formerly the most senior Hamas leader and October 7 terrorist attack mastermind, during a drone strike targeting two other terrorists. Sinwar’s killing appears to have been an accident, as Israeli intelligence said it was unaware Sinwar had been traveling with the other targets.
