At least 20 people have been arrested in the Myanmar town of Taunggok after staging a silent protest on the 20th anniversary of a major uprising.
They were detained after marching while wearing T-shirts which referred to the date of the uprising - "8/8/88".
Activists outside Myanmar, formerly known as Burma, are marking the anniversary with demonstrations.
The 1988 protests drew hundreds of thousands of people onto the streets, but ended with a violent clampdown and the deaths of at least 3,000 civilians.
