Burma's military rulers have accused jailed democracy leader Aung San Suu Kyi and her National League for Democracy of plotting to overthrow the government.
The government said Sunday that the alleged NLD plan to seize power would have incited monks, students, workers and opposition parties to rise up against the ruling council.
The NLD has not responded to the government's allegations.
The accusation against Aung San Suu Kyi and her NLD party comes a day after the military announced the arrest of 12 people accused of planning to carry out assassinations and bomb attacks to create civil unrest.
Authorities arrested Aung San Suu Kyi on May 30th, following a clash between the Nobel Peace Laureate's supporters and a pro-government group. International pressure has been mounting for her release.
In Jakarta Sunday, Burma's Foreign Minister Win Aung said there was no schedule for Aung San Suu Kyi's release. He told reporters he "can not see a timeframe" for it right now.
Win Aung is scheduled to meet with Indonesia's president (Megawati Sukarnoputri) and foreign minister (Hassan Wirajuda) on Monday.
Thailand recently unveiled a draft proposal to mediate Aung San Suu Kyi's release at a meeting of Asian and European countries in Indonesia. The Rangoon government has indicated it is not likely to accept Bangkok's offer.
The NLD won Burma's last parliamentary election by a landslide in 1990, but the military refused to relinquish power. The current government came to power in 1988 after crushing a pro-democracy uprising. Generals have ruled Burma since 1962.
