“We took out thousands of terrorists, including Nasrallah himself and Nasrallah’s replacement, and the replacement of the replacement,” Netanyahu said JERUSALEM/BEIRUT: Prime Minister Benjamin Netanyahu said on Tuesday Israeli airstrikes had killed two successors to Hezbollah’s slain leader, as Israel expanded its ground offensive against the Iran-backed group with a fourth army division deployed into south Lebanon. Netanyahu spoke in a video released by his office hours after the deputy leader of Hezbollah, which is reeling after a spate of killings of senior commanders in Israeli airstrikes, left the door open to a negotiated ceasefire. “We’ve degraded Hezbollah’s capabilities. We took out thousands of terrorists, including (Hassan) Nasrallah himself and Nasrallah’s replacement, and the replacement of the replacement,” Netanyahu said, without naming the latter two. Israeli Defense Minister Yoav Gallant said Hashem Safieddine, the man expected to succeed Nasrallah, had probably been “eliminated.” It was not immediately clear whom Netanyahu meant by the “replacement of the replacement.” Later, Israeli military spokesman Daniel Hagari said Israel knew Safieddine was in Hezbollah’s intelligence headquarters when fighter jets bombed it last week and Safieddine’s status was “being checked and when we know, we will inform the public.” Safieddine has not been heard from publicly since that airstrike, part of an escalating Israeli offensive after a year of border clashes with Hezbollah. The group is the most formidably armed of Iran’s proxy forces across the Middle East and has been acting in support of Palestinian militants fighting Israel in Gaza. “Today, Hezbollah is weaker than it has been for many, many years,” Netanyahu said. Israel’s military said on Tuesday that heavy air strikes against underground Hezbollah installations in southern Lebanon over the prior 24 hours killed at least 50 fighters including six sector commanders and regional officials. The heightened regional tensions kindled a year ago by Palestinian armed group Hamas’ attack from Gaza on southern Israel have escalated in recent weeks to engulf Lebanon.
