The television station of Lebanon's militant Hezbollah group says its leader has discussed attempts to find a resolution to Syria's civil war with Iranian Foreign Minister Mohammad Javad Zarif.

Zarif is in Lebanon on his way to Syria, where he is scheduled to arrive in Damascus later Wednesday.

Iran has said it is preparing to submit a four-point peace plan proposal for Syria to the United Nations. According to some reports, it includes a cease-fire and a "national unity government."

Al-Manar TV said Sheikh Hassan Nasrallah and Zarif talked about attempts "to find solutions in more than one country."

Iran is one of embattled Syrian President Bashar Assad's strongest supporters and the Iranian-backed Hezbollah has sent thousands of fighters to Syria to back government forces.
