The Pakistani Taliban have vowed to resist until the last breath'' as security forces entered two militant-held towns and fought on the outskirts of a third in what could turn into bloody urban battles near the Afghan border. Taliban spokesman Muslim Khan made the defiant statements late Sunday after a top official said the military offensive in the Swat Valley and surrounding areas had killed more than 1,000 suspected militants and would proceed until the last insurgent is flushed out.'' We will fight until the last breath for the enforcement of Islamic law,'' Khan told a news agency in a brief phone call from an undisclosed location. We consider ourselves on the right path.''
