Iran's supreme ruler has called for national unity and urged both sides in a bitter election dispute "not to stoke the emotions of the young", Associated Press reported.
Ayatollah Ali Khamenei's appeal was broadcast Sunday on state TV.
Khamenei has rejected demands by opposition leader Mir Hossein Mousavi to hold a revote. Mousavi says he is the rightful winner, not hardline President Mahmoud Ahmadinejad.
In recent days, the government has widened a clampdown on opposition supporters who allege the presidential election was rigged.
State TV reported Khamenei met with government officials to discuss the election. In comments carried by the station he said: "I admonish both sides not to stoke the emotions of the young or pit the people against eachother. Our people are made of one fabric."
