A senior adviser to Iran's Supreme Leader Ali Khamenei said Friday that his country was not "sabotaging" efforts to achieve a Hezbollah-Israel cease-fire and will back any decision made by the Lebanese government.

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.

He appeared to be urging it to press the militant group, a close ally of Iran, to agree to a deal that could require it to pull back from the Israel-Lebanon border.
