Iran and Syria have agreed to work together to keep Hezbollah from being destroyed in its fight against Israel, Syria sources have said.

The sources, quoted in the Qatar newspaper Al-Watan, said the two governments have agreed that Hezbollah must not be defeated politically or militarily and they have agreed to do all they can to prevent such an outcome, ynetnews.com reported Wednesday.

Israel's failure to defeat Hezbollah thus far is likely to cause the country to turn its sights on Syria, the sources said. They said such a move would cause Iran to get involved militarily, forcing Israel to face a war on multiple fronts.

Israel sent a message to Syria through Jordan, warning the country against arming and supporting Hezbollah, a diplomatic source in Tel Aviv told ynetnews.com. The warning said Israel was aware of weapons convoys traveling from Syria to Lebanon, and that Damascus is frequently the site of meetings between Hezbollah and Iranian officials. The source did not confirm whether the message included a warning of military action against the country.
