Watch: Israeli military simulates war with Hezbollah

The exercise comes after accusations by Israel last month that Hezbollah had carried out "provocative" activity along the Lebanese-Israeli frontier, saying it would complain to the U.N. Security Council. Israel and Hezbollah fought a month-long war in 2006 that ended in a stalemate, followed by a UN-brokered truce, which barred Hezbollah from conducting military activity along the frontier.
