The leader of Lebanon’s militant Hezbollah group said early on Saturday that its fighters will not disarm as long as Israeli troops remain in southern Lebanon and the Israeli air force regularly violates Lebanese air space. Naim Kassem addressed supporters in a speech broadcast on Hezbollah’s television station. Kassem took over Hezbollah after Israeli airstrikes killed longtime leader Hassan Nasrallah, his successor Hashem Safieddine and other top Hezbollah figures last year, decimating the group’s leadership.

Kassem said Hezbollah had implemented its commitments related to the US-brokered ceasefire that halted the fighting in Hezbollah’s latest, 14-month war with Israel. Since the ceasefire went into effect in late November, Israeli airstrikes have killed scores of people in Lebanon including civilians and Hezbollah members. Israel says it’s targeting Hezbollah holdouts in southern Lebanon.
