Pakistan President Pervez Musharraf has ordered a crackdown on 30 militant groups in the port city of Karachi after security agencies presented him a report highlighting their activities.

"A comprehensive report covering all aspects of terrorism in Karachi, prepared by the Interior Ministry in collaboration
with the provincial government and law-enforcement agencies, was presented to Musharraf. He ordered an immediate crackdown against these groups," a media report said on Saturday.

The report analysed violence in Karachi in the past two-and-a-half years and said around 30

terrorist groups operated from the city.

Fifteen of these groups took part in sectarian violence, while the rest are jehadi outfits fighting against Western interests, the Daily Times quoted officials as saying.

The report identified 21 top terrorists, mostly locals. The wanted list included the names of Amjad Farooqi, Asif Chotoo, Naveedul Hassan, Raza Imran and Saud Memon.
