Ayatollah warns Iranian politicians

State radio says Iran’s Supreme Leader Ayatollah Ali Khamenei has told politicians to be careful in their stances on the country’s post-election unrest, saying that disturbing security is “the biggest vice.”

Ayatollah Khamenei’s comments appear to be aimed at warning opposition politicians against making any moves that would encourage further protests like the ones that shook the country following the disputed presidential election on June 12.
