The government on Friday moved an army brigade to Tank district, officials said. Tank District Police Officer (DPO) Mumtaz Zarin told Daily Times that the army had been called in to improve security and to stop incursions from the tribal areas. He, however, refused to comment on how many soldiers were being deployed there, but said the army deployment was a gradual process. “No operation is being considered at the moment,” the DPO added. NWFP Information Minister Asif Iqbal Daudzai ruled out a military operation in the area, saying that the army had been summoned to assist the local administration in maintaining law and order. “We were against use of force in Islamabad... how can we agree on an operation in the NWFP?”
