Lebanese Prime Minister Saad Hariri has arrived in Tehran to seek Iranian support for efforts to keep Lebanon stable amid tensions over a UN probe into the assassination of his father, Rafik Hariri.
During his visit, Hariri will meet Iranian President Mahmud Ahmadinejad and other officials.
Lebanon's fragile unity government, which includes the Iranian-backed Hezbollah, has been struggling ahead of expected indictments by the UN tribunal investigating the 2005 assassination.
Speculation that Hezbollah members will be indicted in the case has fueled fears of a new crisis in Lebanon.
