More signs pointing to a ground war:
The Israel Defense Forces will be calling up additional reserve battalions, sending thousands more soldiers to fight Hezbollah on the northern border and Palestinian militants in the Gaza Strip, the army said Friday.
The IDF said the call-up would likely come later in the day.
The decision comes on the heels of a significant expansion of the ground operations in the north, as the IDF sent thousands of troops into southern Lebanon on Thursday. Three reserve battalions have already been called up.
