Al Jazeera’s political analyst Marwan Bishara says Hezbollah losing contact with its leader Hashem Safieddine shows that Israel is able to “deliver one blow after another” to the group. “It is also significant that it proves there is an intelligence breach when it comes to Hezbollah, allowing Israel to locate and attack one leader after another,” he said. “From the rigging and detonating of communication devices and the assassination of one Hezbollah leader to another, all the way to Hassan Nasrallah and now apparently his successor, underlines that either Israel is getting help or it has infiltrated Hezbollah in various ways digitally, electronically or perhaps with human resources,” he added.
