ON a humid May morning in 1987, Vietnamese security officers burst into a monastery in the Dong Cong quarter of Ho Chi Minh City and dragged out a dozen monks and their followers.
Under the stone floors of the ancient temple, surrounded by faded colonial villas and potholed alleyways with small tea houses, police stumbled upon the seeds of a dying revolt against Vietnam's leaders.
According to reports that would later filter out of the closed military court where they were tried, the saffron-robed monks fought with pointed sticks and knives alongside ''foreign infiltrators'' trained abroad.
It was the link Hanoi had long sought to establish between the fiercely independent Buddhist movement and remnants of the former South Vietnamese army seeking to overthrow the communists who defeated them in 1975.
Six years later the muted rumble of dissent is threatening to boil over again in Vietnam's monasteries following unrest in the historic city of Hue, long recognised as the symbol of Buddhist power.
A senior monk was hauled in for questioning after one of his followers burned himself to death in the 150-year-old Linh Mu pagoda in protest at sweeping arrests by internal security police.
The self-immolation, on May 21, led to street protests by monks, including a reported clash with police after they blocked a key road.
