BANGKOK, August 6, 2008 (AFP) - US President George W. Bush vowed to 'seek an end to tyranny' in Myanmar and called on the regime to free democracy leader Aung San Suu Kyi, according to a copy of a speech he will deliver Thursday.

'We seek an end to tyranny in Burma,' he was to say, referring to the country by its previous name.

'America reiterates our call on Burma's military junta to release Aung San Suu Kyi and all other political prisoners. And we will continue working until the people of Burma have the freedom they deserve.'
