Israel says calling up four more reserve brigades for northern 'operation'

The Israeli army mobilized four additional brigades to be deployed in missions along the northern border, the military said on Tuesday, after it claimed ground operations targeting Hezbollah positions in southern Lebanon overnight.

"This will enable the continuation of operational activity against the Hezbollah terrorist organization and the achievement of operational goals, including the safe return of the residents of northern Israel to their homes," the army said in a statement.

There were no signs of ground combat late Monday and early Tuesday in southern Lebanon and Hezbollah, an army source, and the UNIFIL said they saw no sign of Israeli forces entering Lebanon.
