The device was believed to have been left at the site previously rather than planted recently, though the circumstances remained under investigation.IDF forces have been operating in Majdal Zoun for several weeks as part of efforts to locate weapons, dismantle Hezbollah military infrastructure and clear the area.Strikes in al-Mansouri, LebanonDuring those operations, troops reportedly uncovered significant underground infrastructure and a Hezbollah compound used for drone activity.The strikes in southern Lebanon continued throughout the night. Lebanon’s Hezbollah-affiliated Al Mayadeen network reported that Israeli Air Force fighter jets struck the towns of al-Mansouri and Burj al-Shamali in the Tyre area.According to the report, three drone strikes were also carried out in the Burj al-Shamali area, and rescue forces evacuated several wounded people from the scene. At the same time, the IDF reportedly fired artillery shells toward the Ali al-Taher ridge area in southern Lebanon.
