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.

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.

Israel launched airstrikes in the Hezbollah-controlled southern suburbs of Beirut, flattening buildings for a fourth consecutive day.
