Thousands flee Pakistan valley as truce crumbles

Black-turbaned Taliban militants seized government buildings, laid mines and fought security forces Tuesday in the Swat Valley, as fear of a major operation led thousands to pack their belongings on their heads and backs, cram aboard buses and flee the northwestern region. The collapse of a 3-month-old truce with the Taliban means Pakistan will now have to fight to regain control of the Swat Valley, testing the ability of its stretched military and the resolve of civilian leaders who until recently were insisting the insurgents could be partners in peace. The government feared the refugee exodus could reach 500,000. The developments brought Islamabad's faltering campaign against militancy into sharp focus as President Asif Ali Zardari was preparing for talks Wednesday in Washington with President Barack Obama and Afghan President Hamid Karzai on how best to counter an increasingly overlapping spectrum of extremist groups behind surging violence in the neighboring countries.
