Iranian media says police have set up a special unit to monitor Web sites and fight Internet "crimes," in a possible attack on the opposition. Police Colonel Mehrdad Omidi, who heads the Internet crime unit, told Mardomsalari newspaper Saturday that the unit will fight "insults and spreading of lies," terms widely used by the judiciary to describe opposition activities. Iranian authorities have banned most Web sites linked to Iran's opposition or those containing articles supporting the reform movement. The opposition has no access to state media and has been promoting its message largely through the Internet.
