The 30-year-old Italian died from a gunshot wound, Israel’s rescue service said on Friday night, the Jewish holy day. Israeli media reported that the assailant was an Arab citizen of Israel, from the northern town of Kafr Qasem. The militant group has vowed to strike back, but, like Hamas, is wary of an escalation. Although Israel said Hamas was behind the attack from Lebanon, it is widely believed that Hezbollah must have greenlighted the move. Huge protests against the coalition’s proposed judicial overhaul have included large numbers of military reservists, raising concerns about operational readiness.
