Lebanese Prime Minister Najib Mikati has expressed hope that a ceasefire could be reached soon to end fighting between Israel and Iran-backed Hezbollah that has shaken his country and raised fears of a ground invasion.

Mikati welcomed the call for a truce but said the key to its implementation is whether Israel, which has been moving troops closer to Lebanon, is committed to enforcing international resolutions.

Asked if a ceasefire could be secured soon, Mikati told Reuters: "Hopefully, yes."

Mikati’s caretaker administration includes ministers chosen by Hezbollah, widely seen as the country’s most powerful political force.

The ceasefire would apply to the Israel-Lebanon "Blue Line," the demarcation line between Lebanon and Israel, and would allow the parties to negotiate towards a potential diplomatic resolution of the conflict, a senior Biden administration official said.

UN Special Coordinator for Lebanon Jeanine Hennis-Plasschaert on Thursday welcomed the call for an immediate 21-day ceasefire to allow the space for diplomacy to succeed.
