Ayatollah Ali Khamenei has accused the US of trying to infiltrate Iran through "money and sex," and says that Iranians must be careful not to fall into the "trap."

Khamenei made his comment to the commanders of the Islamic Republic's Revolutionary Guard. He emphasized that there are strong concerns over "infiltration" and that efforts must be focused on the fighting the US rather than on internal squabbles.

Associated Press reports that many take today's remarks as support for the numerous arrests of pro-Western journalists and authors.
