Tensions between Israel and Hezbollah escalated significantly on Wednesday, marking the most severe attacks from Lebanon since the conflict began four months ago. Israel retaliated with fighter jets targeting Hezbollah positions in response to the assaults on Israeli towns and an army base. Lebanon’s political instability, evidenced by the absence of a president and only a caretaker PM, complicates governance over Hezbollah, a group recognized as both a political party and a militant organization by various entities.
