Myanmar's military regime arrested at least three activists, including leaders of a pro-democracy group that staged a rare protest against massive fuel-price hikes, the official media said on Wednesday.
The state-run New Light of Myanmar newspaper said the activists were detained on Tuesday night for attempting to undermine the "stability and security of the nation".
A Washington-based activist group, the US Campaign for Burma, said in a release that virtually the entire leadership of the 88 Generation Students was taken to a detention center in Yangon.
Members of the 88 Generation Students were at the forefront of the 1988 pro-democracy uprising and were given lengthy prison terms after the rebellion was brutally suppressed by the military.
Five university students and three members of another activist group were also arrested in separate sweeps by the authorities, the release said.
The arrests came two days after the group led more than 400 people in a protest march through Yangon against the doubling of fuel prices on August 15.
Those reportedly arrested included Min Ko Naing, one of Myanmar's most prominent activists, Mya Aye, Pyone Cho and Yin Htun.
Three members of the Myanmar Development Committee, which had called for a nationwide protest against the sudden hikes, were also arrested along with five university students, who were putting up posters demanding the reduction of prices on fuel and basic commodities.
Rumours circulated in Yangon that a nationwide protest against the hikes would be staged on Wednesday.
