Nasrallah said Thursday that his Syrian allies would provide his forces with weapons with which to respond to recent Israeli airstrikes on Damascus.
"The Lebanese resistance announces that it is ready to receive any sophisticated arms even if it is a game changer and we are ready to obtain and safeguard such weaponry and use it to defend our people and country," he said.
Ahmad Fatfat, a member of the pro-Western March 14 political alliance in Lebanon, told The Daily Star newspaper that Nasrallah was seemingly acting on behalf of the state.
"What they used to claim that the resistance is in defense of Lebanon is no longer valid," he said.
His March 14 counterparts said Nasrallah's claims would push Lebanon closer to war with Israel.
A U.N. resolution passed to 2006 war between Israeli and Hezbollah. Hezbollah under the terms of the resolution is called on to disarm while Israel was reminded of its obligation to respect Lebanese sovereignty. Israeli airstrikes were launched allegedly from Lebanese airspace.
