Lebanese state media and eyewitness reports confirmed a large explosion occurred on Monday in the southern village of Mansouri, located in the Tyre district near the border with Israel. According to Lebanon’s National News Agency (NNA), the blast was caused by the Israeli military, which has maintained a presence in a self-declared "security zone" extending roughly 10 kilometers into southern Lebanon.

The explosion was reportedly powerful enough to be heard in the city of Tyre and surrounding villages. AFP correspondents on the scene witnessed substantial smoke rising from Mansouri, which appeared heavily damaged following the detonation.

Mansouri lies approximately nine kilometers south of Tyre and about 10 kilometers north of the Israeli border. The area has experienced repeated Israeli strikes and artillery shelling over recent weeks, despite a ceasefire that began in June. During the ceasefire, Mansouri's local municipality had informed residents they could return to their homes but advised avoiding areas within the so-called “security zone” controlled by Israeli forces.

In late August, Israeli military authorities ordered the evacuation of Mansouri ahead of a full occupation. Since then, Israeli forces have carried out regular demolitions and controlled detonations in the town, activities visible to residents throughout the Tyre region.

Israel continues to maintain troops inside this buffer zone in southern Lebanon, where it has conducted widespread demolition operations in the villages under its control. The military presence and ongoing operations occur amid persistent tensions despite the ceasefire agreement.
