Over 140 militants were killed and 1100 others, including 600 foreigners, detained in Pakistan since the 9/11 terror attacks on the US, President Pervez Mushrraf said on Friday.
The government has already outlawed extremist organisations and issued a list of some 400 leaders of these banned outfits besides identifying 89 books and pamphlets to stop preaching of hatred and violence, he said at the launch of the National Public Safety Commission (NPSF) here.
The police have lost 400 men while acting against terrorists since the September 11, 2001 terror strikes, he said adding some 600 foreign and 500 sectarian terrorists have been rounded by the police and the law-enforcing agencies.
"Cities have generally been cleansed of terrorists", he said, while crediting all security agencies for unearthing almost all the important terrorist acts in the country and killing about 140 militants in last five years.
"Terrorism has to be met with force and law enforcement agencies are doing a great job but there is a strategy to deal with extremisms as it involves change in the mindset", he said.
"In case of crimes like car-snatching, an individual suffers but if we don't control extremism, the entire nation will suffer", Musharraf said.
He asked police and law-enforcing agencies to check the misuse of loudspeakers in places of worship as also people who preach sectarian discord and incite people to violence.
He also asked them to keep a close vigil on publication, printing and distribution of hate material and called for a strict action against those involved in such activities.
