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

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.
