It added, "As part of his role, Yassin collaborated intensely with all of Hezbollah's offensive units, was personally involved in the planning of terror attacks that were executed during the war against Israeli civilians and soldiers, and planned additional attacks to be carried out in the coming days."

Meanwhile, Lebanon launched an attack on Israeli territory following the assassination of its leader, Hassan Nasrallah. In a post on social media, IDF said, "Sirens sounded in the area of Jerusalem following a launch from Lebanon into Israeli territory."

The IDF announcement of another strike in Beirut came after the death of Hezbollah leader Hassan Nasrallah. Notably, a day before, IDF confirmed the killing of Hassan Nasrallah in the airstrikes carried out by the Israeli military in Beirut.

In a statement, IDF said, "Hassan Nasrallah will no longer be able to terrorise the world." Nasrallah was targeted at Hezbollah's main headquarters in the southern suburbs of Beirut, a Hezbollah stronghold known as the Dahiyeh, on Friday. The headquarters is underground, beneath residential buildings in the Dahiyeh, according to the IDF.

Meanwhile, IDF escalated their operation against Hezbollah by conducting targeted strikes on strategic weapon production facilities.

In a post on X, the IDF said, "Following precise intelligence, last night, the IDF intensified its operations against Hezbollah's force build-up through a series of targeted strikes on key weapon manufacturing sites. These included a facility used to produce and assemble missile and rocket launchers in southern Lebanon, as well as another site in the Beqaa Valley."
