Top Lebanese officials have urged Washington and Paris to press Israel to uphold a ceasefire, after dozens of military operations on Lebanese soil that Beirut has deemed violations, two senior Lebanese political sources told Reuters on Tuesday.

In its strongest threat since last week's deal to end 14 months of conflict, Israel said it would hold Lebanon responsible for failing to disarm militants who violate the ceasefire.

Deadly Israeli strikes on south Lebanon and Hezbollah rocket launches on an Israeli military post on Monday have put a U.S.-brokered ceasefire between the two in an increasingly fragile position

When Israel struck Hezbollah targets it was accused of breaking the agreement, but if it does not respond to violations, Hezbollah will have carte blanche to threaten Israel

A deal to end the fighting between Israel and Hezbollah in Lebanon went into effect Nov. 27, but there have been multiple claims of cease-fire violations.

Israel will gradually withdraw its forces over 60 days as Lebanon's army takes control of territory near its border with Israel to ensure that Hezbollah does not rebuild its infrastructure there, Biden said.
