"The battle with us is going to be all over occupied Palestine," the black-turbaned Nasrallah said. "From the border with Lebanon to the frontier with Jordan to the Red Sea."
"The Israelis should listen well to me. From Kiryat Shemona to Eilat," Nasrallah said referring to a northern Israeli town near the border with Lebanon to the southern resort town of Eilat on the Red Sea.
Since the 2006 war ended, both Israeli and Hezbollah officials have been warning each other that the next battle between the two groups will be more destructive.
Some Israeli generals had spoken of the "Dahiya doctrine," named after the Beirut suburbs considered a Hezbollah stronghold where Israel turned dozens of buildings to piles of debris in 2006.
In August, Nasrallah said Hezbollah will transform the lives of Israelis to "hell" if Israel attacks Lebanon, adding that the group would not hesitate to hit targets that would leave tens of thousands of Israelis dead.
Hezbollah was created in 1982, weeks after Israel invaded Lebanon. Israel withdrew in 2000 to a border drawn by the U.N., but Lebanon says Israel still occupies a slice of its territory.
