Iran's foreign minister has met with Syrian officials about a senior Hezbollah commander killed this week in a car bombing in the Syrian capital, Damascus.
Iranian officials say Manouchehr Mottaki also held talks Friday in Damascus with leaders of two Palestinian militant groups, exiled Hamas chief Khaled Mashaal and Ramadan Abdullah of Islamic Jihad.
Iran and Syria are key supporters of Hezbollah, which blames Israel for Wednesday's assassination of Hezbollah commander Imad Mughniyeh. Hezbollah's leader Hassan Nasrallah has threatened "open war" on Israel.
Israel has denied involvement in the car bombing.
Mughniyeh -- one of the world's most wanted terrorists -- was implicated in deadly attacks on Western and Israeli targets in the 1980s and 1990s.
U.S. officials linked Mughniyeh to some of the bloodiest attacks in the past 25 years. They include the 1983 bombings of the U.S. Marine barracks in Lebanon and a Jewish community center in Buenos Aires, Argentina in 1994.
Mottaki attended Mughniyeh's funeral on Thursday in Beirut.
