Hezbollah's chief on Thursday rejected a conditional truce announced by Lebanese and Israeli envoys, demanding instead a comprehensive ceasefire and full Israeli withdrawal as he threatened northern Israel with new attacks. Naim Qassem's message came after Lebanese and Israeli representatives in the United States agreed to a conditional ceasefire that Lebanon's president called the "last chance" for a durable end to the fighting. Lebanon was drawn into the wider Middle East war when Hezbollah attacked Israel to avenge the February 28 killing of Iran's supreme leader.
