Tens of thousands of Burmese defied warnings by the military junta, and staged another day of marches in cities across the country.
In Rangoon, monks led the way from the revered Shwedagon Pagoda, which has become a focal point of the growing protests.
They have been joined by large numbers of students and supporters who until Monday had stood on the sidelines cheering the monks.
Along with Buddhist flags, some marchers carried flags bearing the image of a fighting peacock, which was used by students in the 1988 pro-democracy uprising.
The marching took its toll on the monks' feet and some had to stop for medical treatment
The protesters took to the streets even though the junta warned it would "take action" after some 100,000 people marched on Monday.
The government is blaming rogue dissidents for the unrest.
The international community fear a repeat of 1988, when government troops brutally suppressed a popular uprising, killing some 3,000 people.
