Israeli forces have crossed the Litani River and captured Beaufort Castle in southern Lebanon, marking the deepest military incursion into Lebanese territory in 26 years.

The operation represents a significant escalation in Israel's military campaign against Hezbollah in southern Lebanon. The capture of Beaufort Castle, a strategic mountaintop position, gives Israeli forces control of a key vantage point in the region.

The Litani River crossing is particularly significant as it represents the furthest Israeli forces have advanced into Lebanese territory since their previous major operation in the area. The river has historically served as an important geographical boundary in the region.

Beaufort Castle sits atop a strategic mountain that overlooks much of southern Lebanon and northern Israel. The medieval fortress has changed hands multiple times throughout various conflicts in the region and is considered a tactically important position for controlling movement in the area.

The Israeli military operation appears to be part of ongoing efforts to push back Hezbollah forces from Israel's northern border. The extent and duration of the Israeli presence in the captured areas remains unclear.
