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.

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

Israel has stepped up strikes on the city’s southern suburbs in recent days, an area Israeli officials say hosts Hezbollah militants and infrastructure.
