Hamas leader Yahya Sinwar’s last act of defiance, caught on drone camera and televised the world over, has spawned a new Arab phrase for resistance, and symbolising the unwavering Palestinian spirit of fighting to the end. Though it is unclear who first used the term but “Asa al Sinwar”, Arabic for “Sinwar’s Stick”, has become the rallying cry for social media users since the former political bureau head of Hamas was caught on camera moments before his death, throwing a stick at a drone inside a damaged building in Gaza.
