Hezbollah is considering a US-Israeli ceasefire proposal, sources told CNN, as diplomatic efforts to end the conflict between Israel and the Lebanese militant group intensify.

Lebanon's caretaker Prime Minister Najib Mikati has appeared to encourage Tehran to convince Hezbollah, which it supports, to agree to a deal that could require the militant group to withdraw from the Israel-Lebanon border.

Iran backs any decision taken by Lebanon in talks to secure a ceasefire with Israel, a senior Iranian official said on Friday, signaling Tehran wants to see an end to a conflict that has dealt heavy blows to its Lebanese ally Hezbollah.
