A top Iranian official has pledged his country's unwavering support for Lebanon after talks with Lebanese leaders on the Israel-Hezbollah war.

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.

As a top adviser to Iran's supreme leader Ali Khamenei visited Lebanon for talks, Lebanese officials said a U.S. proposal for a cease-fire deal had been passed on to Hezbollah.

Lebanon's caretaker prime minister on Friday asked Iran to help secure a cease-fire in the war between Israel and Hezbollah and appeared to urge it to convince the militant group to agree to a deal that could require it to pull back from the Israel-Lebanon border.
