The killing of Israel's most wanted enemy Yahya Sinwar has been hailed as vindication for Prime Minister Benjamin Netanyahu, but in a country weary after a year of war it also raises pressure on him to end the fighting and save the hostages still in Gaza.

Earlier, Gaza's Hamas-run Civil Defence Agency said at least 22 people were killed in an Israeli strike on a school building in northern Gaza. The Israeli military said it conducted a "precise strike", claiming Hamas was using the site as a command centre, which the group has denied.
