Israeli air strike kills Hezbollah leader Nasrallah, robbing Iran of top ally The Israeli military said on Saturday it had "eliminated" Hezbollah leader Hassan Nasrallah in a strike on the group’s headquarters in Beirut. Nasrallah's death is a major blow to both Hezbollah and Iran, depriving Tehran of an influential ally who helped build Hezbollah into the key ally in Iran's network of groups in the Arab world.
