An Israeli tank column has crossed the Litani River and is advancing toward the city of Nabatieh, the administrative centre of Nabatieh Governorate in southern Lebanon, Al Hadath television reported.

According to the broadcaster, Hezbollah fighters attempted to slow the advance of Israeli forces, putting up fierce resistance in the areas of Arnoun and Al-Ghandouriya. Clashes are reportedly still continuing in some locations.

Israeli artillery has shelled the area around the medieval Beaufort Castle near Nabatieh, where movements of opposing forces were observed. Several settlements have fallen within the bombardment zone.

There are reported casualties and injuries among civilians, although the exact number has not yet been confirmed.

Israeli military commanders had earlier instructed residents of 14 communities in the Western Bekaa region to evacuate their homes ahead of air strikes targeting Hezbollah bases and military facilities in the area.

Similar warnings were also issued to residents of 12 villages in the border district of Tyre.
