U.S. Secretary of State Hillary Rodham Clinton faced sharp rebukes from Pakistani audiences Friday, including one woman who accused the U.S. of conducting "executions without trial" in aerial drone strikes. Slapping back, Clinton questioned Pakistan's commitment to fighting terrorists.

"Somebody, somewhere in Pakistan must know where these people are," Clinton said in an exchange almost as blunt as her exasperated comments a day earlier that Pakistani officials lacked the will to target al-Qaida.
