Hezbollah, Iran’s most powerful regional ally, has signaled privately that it does not intend to attack Israel, but Lebanon’s military has bolstered its presence in the country’s south to prevent rocket fire.

A top U.S. official visiting the Lebanese capital on Thursday discouraged Tehran-backed armed group Hezbollah from intervening in the war between Iran and Israel, saying it would be a "very bad decision".

U.S. envoy Thomas Barrack visited Beirut to urge reforms, support army efforts, and warn Hezbollah against joining the escalating Israel-Iran war.
