Hezbollah leader Sayyed Hassan Nasrallah threatened on Sunday to fire "thousands of rockets" at Israeli cities if Lebanon was attacked.
The Iranian-backed terror group was "able to target the entire occupied territories, from the Lebanese border to Jordan to the Red Sea, from Kiryat Shmona to Eilat", Nasrallah said, according to Lebanon's as-Safir newspaper.
In a speech in Southern Beirut to mark the Shiite festival of Ashura, Nasrallah urged Arab and Islamic governments to arm "resistance factions" in Gaza.
Nasrallah vowed to bomb Tel Aviv and other Israeli cities with thousands of rockets in any future war.
"If Israel is shaken and confused by a small number of Fajr-5 rockets, less than ten in eight days, how will it cope with thousands of rockets that will hit Tel Aviv if Lebanon is attacked?" he said.
Echoing remarks made last week by Iran's parliamentary speaker Ali Larijani, Nasrallah urged Arab and Islamic governments to send military aid to Gaza.
"Gaza and Palestine don't only need your sympathy and visits, but they also need your weapons and money," Nasrallah said, according to As-Safir.
