Iranian police will launch a crackdown this week on "indecent Western-inspired movements" such as rappers and satanists, state radio said. The move signals a widening of a clampdown on "immoral" conduct launched last year against women flouting rules dictating that women cover their heads and disguise the shape of their bodies in public, in line with Iran's Islamic system.

State radio quoted commander Ahmad Rouzbehani of the police moral security unit as saying the new campaign would take effect nationwide on May 17 and that offenders would initially receive a "warning and information." The crackdown against what clerics see as "corrupt" Western influence coincides with rising pressure on Iran by the West over its nuclear programme. The United States and its allies say Iran wants to build an atomic bomb, which Tehran denies. Late last month Iranian media said police would launch a crackdown in May on small companies which fail to enforce strict religious dress codes.
