BBC Persia just released a statement by Khamenei, who said in part:
The security of the nation and the will of the faithful people of the Islamic Republic will not bend under pressure. … The candidates (referring to Mousavi and Karroubi) must take into account that their regional actions/behaviors have an effect at the national level.
NIAC adds:
It seems that his intention here is to warn Mousavi and Karroubi that their actions in Tehran are disrupting the whole security structure of the establishment.
