Israel on Sunday struck Lebanon’s capital, Beirut, for the first time since June, saying it targeted Hezbollah’s chief of staff and warning the Iran-backed militant group not to rearm and rebuild a year after their latest war. Hezbollah said the strike, launched almost exactly a year after a ceasefire ended that Israel-Hezbollah war, threatened an escalation of attacks — just days before Pope Leo XIV is scheduled to visit Lebanon on his first foreign trip.
