Israel's defense chief warns that the truce with Lebanon's Hezbollah is at risk due to the failure of Lebanese troops to eliminate Hezbollah infrastructure in the buffer zone. If this condition is not met, Israel may act on its own to ensure the safe return of its residents. Hezbollah's leader warned that its fighters could strike Israel if Israeli troops don't leave the south by the end of the month. Lebanon's Parliament Speaker will meet with a US envoy to discuss the situation.
