Lebanon's Hezbollah chief Hassan Nasrallah said in a speech on Friday that all of Lebanon would be exposed if the group did not react to the assassination of deputy Hamas chief Saleh al-Arouri in Beirut.

Nasrallah added that its current operations on the southern borders opened a "historic opportunity" for Lebanon to liberate its land occupied by Israel and that the Islamic resistance in Iraq also has a "historic opportunity" to get rid of the U.S. presence in that country.
