"Threats of bloody retribution and accusations of American involvement erupted across Pakistan's tribal areas yesterday after the missile strike that killed 80 people in a radical madrasa. An estimated 20,000 tribesmen crowded into Khar, six miles from the school that was shredded by air strikes on Monday. Cries of "Down with America" rang out as radical clerics addressed the turbaned protesters, many of whom brandished Kalashnikovs or rocket launchers."
