Israel's military said its troops began limited ground raids against Hezbollah targets in the border area of southern Lebanon early on Tuesday, as a ground invasion by its troops appeared to be getting under way.
Calling the campaign Operation Northern Arrows, the military said in a statement that the targets were in villages close to the border and posed "an immediate threat "to communities in northern Israel." It said the air force and artillery were supporting ground forces with "precise strikes."
The White House and the U.S. State Department did not immediately respond to a request for comment.
Hezbollah's deputy leader Naim Qassem said on Monday that "the resistance forces are ready for a ground engagement."
