Hezbollah declared on Friday its readiness for a protracted confrontation with Israel, as Israeli forces threatened significant damage to Lebanese infrastructure.

Hezbollah leader Naim Qassem stated his group is prepared for a long battle, emphasizing its existential nature. "We have prepared ourselves for a long confrontation, and God willing, they (Israelis) will be surprised on the battlefield," Qassem said. "This is an existential battle, not a limited or simple battle."

Israel acknowledged striking a key Litani River bridge, describing it as a vital crossing for Hezbollah. Israeli Defense Minister Israel Katz warned that Lebanon would pay an "increasing price in damage to Lebanese national infrastructure" unless Hezbollah is disarmed.

Earlier, Lebanese President Joseph Aoun had offered direct negotiations with Israel, but reported no response. Israeli Prime Minister Benjamin Netanyahu had previously cautioned Lebanon about allowing Hezbollah's continued operations.

Israeli forces also bombed several roads in southern Lebanon and hit a UN Nepalese battalion. Meanwhile, UN chief Antonio Guterres urged both Hezbollah and Israel to "stop the war" during a visit to Beirut, launching a humanitarian appeal for Lebanon.

Israeli strikes continued, with reports of casualties in southern Lebanese villages. The conflict has led to widespread displacement and tragic loss of civilian life.
