Police blocked pro-democracy leader Aung San Suu Kyi from holding her rallies for the third straight weekend Sunday.
Barriers on roads leading to her home were put up early Saturday in an attempt to stop the Nobel Prize laureate from delivering speeches. Her weekend addresses had become a regular feature of Rangoon's political life since her release from house arrest last year.
Seizing power eight years ago, the military has been trying to suppress Ms. Suu Kyi and her political party, the National League for Democracy.
It escalated its campaign last month, making sweeping arrests and attacking the movement almost daily in the state-controlled media.
Ms. Suu Kyi was under house arrest for six years for her role in a 1988 democracy uprising that was brutally put down by the military regime.
