ANKARA, May 26 (Reuters) - Iran's Supreme Leader Ayatollah Ali Khamenei called for vigilance against the West's "soft war" aimed at weakening the clerical establishment, state television reported on Thursday.

"Our officials and all parts of the establishment should be vigilant about the West's continued soft war against Iran ... the enemies want to weaken the system from inside," Khamenei said.
