Thousands of Iranian government supporters staged rallies on Friday denouncing opposition students who burned photos of the Supreme Leader Ayatollah Ali Khamenei in protests this week.
Iranian state TV says the rallies took place in Teheran and other cities after Friday prayers.
Participants marched and chanted: "Down with the US" and "Down with Israel." They read out statements saying the opposition couldn't "achieve their miserable aims by insulting" Iran's supreme religious leader.
The marches came after tens of thousands of opposition students protested at universities around Iran on Monday. Some burned pictures of Khamenei, breaking a taboo against insulting the leader. State TV aired footage of the picture burning, stoking hard-liner outrage.
