White House Says America's Goal Is to Reduce Tensions

U.S. and Indian officials have suggested that the attackers came from Pakistan, a charge Pakistan's President Asif Ali Zardari denied Tuesday.

When asked about reports that the lone captured attackers has admitted that he was trained in Pakistan, Zardari told CNN's Larry King: "We have not been given any tangible proof to say that he is definitely a Pakistani. I very much doubt, Larry, that he's a Pakistani."

The United States is conducting its own intelligence investigation into the origin of the Mumbai attackers. Sources say that there are indications they came from Pakistan, but caution that American intelligence has not yet been able to determine that conclusively.
