Hezbollah rejected a renewed ceasefire agreement between Israel and Lebanon hours after the United States announced the deal Wednesday night, casting immediate doubt on any halt to the fighting.
Washington said the agreement was reached following a fresh round of diplomatic talks, but the militant group moved quickly to repudiate the terms, the Wail confirmed from reporting by BBC News.
The rejection leaves the ceasefire without the buy-in of one of the principal armed parties to the conflict, undermining its practical force before it could take effect.
Israel has not yet formally responded to Hezbollah's repudiation as of Wednesday night. The Lebanese government's position on the collapse of the deal has not been confirmed.
The announcement had been framed by US officials as a path toward stabilising the Lebanon front following weeks of cross-border strikes. Hezbollah's flat refusal narrows that path considerably.
Further diplomatic contact between Washington and regional parties is expected in the coming days as officials assess whether a revised framework is viable.
