"In recent days, IDF troops from the 91st division have begun limited and targeted ground operations against key Hezbollah strongholds in southern Lebanon, aimed at enhancing the forward defence area," the military said in a statement.

"This activity is part of broader defensive efforts to establish and strengthen a forward defensive posture, which includes the dismantling of terrorist infrastructure and the elimination of terrorists operating in the area, in order to remove threats and create an additional layer of security for residents of northern Israel," it said.

"Prior to the troops' entry into the area, the IDF conducted strikes using both artillery and the Israeli Air Force against numerous terrorist targets in order to mitigate threats in the operational environment."

Lebanon was dragged into the Middle East war on March 2 when Iran-backed Hezbollah attacked Israel in response to the killing of Iranian supreme leader Ayatollah Ali Khamenei in US-Israeli strikes, with Israel launching air raids on the neighbouring country and troop incursions into border areas.
