The orders came after Hezbollah fired on Israel, saying it was avenging the killing of Iran’s supreme leader, Ayatollah Ali Khamenei, and acting in defense of Lebanon. The Lebanese government answered by banning military activity by Hezbollah, declaring that only the state can make decisions about war and peace. President Joseph Aoun on Monday said Hezbollah showed “no regard for the interests of Lebanon or the lives of its people.”
