ISLAMABAD (NNI) - NWFP Chief Minister Amir Haider Khan Hoti has said that the extremist activities have increased after release of Tehrik Nifaz Shariat-i-Muhammadi (TNSM) leader Sufi Muhammad. Talking to the BBC, he said some hidden forces were trying to sabotage the peace process and want to create law and order situation especially in Swat. To a query, he said the formulation of policy was responsibility of the elected government. The masses gave mandate to the present government and every one will see positive changes soon. He said the policy of the previous government was to force the people and find out solution to the issue by use of force. He said, "We brought change in the policy that the forces should be used as a last and the issues should be resolve through dialogue, which we are doing." To another question, he said peace in the tribal areas is need of the hour and Pakistan is pre-requisite for peace and stability in Afghanistan.  The tribal belt can contribute or cooperate in this regard, he added. He said that the tribal belt is under control of the federal government and not the provincial government. The border crossing or activities are related to the FATA. "We are seeing the solution of the problem. We have our own traditions and culture. Our elders always resolved the issues or disputes through jirgas," the Chief Minister said.
