WASHINGTON, Oct 19 (Reuters) - President George W. Bush announced further U.S. sanctions against Myanmar's military rulers on Friday, saying they had continued to defy international demands to "stop their vicious persecution." Imposing the second package of U.S. measures in less than a month, Bush said he was adding more of Myanmar's leaders to a list of those already facing financial and travel sanctions and that he had instructed the U.S. Commerce Department to tighten export controls on Myanmar.
