Israel's President Isaac Herzog on Thursday called for swift action to bring back hostages held in Gaza, as he hailed the killing of Hamas leader Yahya Sinwar by Israeli forces.

Herzog on social media platform X said the slain Hamas chief was the mastermind of the October 7, 2023 attack that triggered the ongoing war and "has for years been responsible for heinous acts of terrorism against Israeli civilians", also calling on Israeli leaders to "act in every way possible to bring back" the remaining hostages.
