Burma's military government has blamed communists and an exiled student group for three bomb blasts this week in a northern town.
The three explosions occurred Monday in Monywa town, near where democracy leader Aung San Suu Kyi was arrested in May.
Official media said the bombings, which caused no injuries or damage, were carried out with the intention of disturbing peace and tranquility and to cause panic.
The blasts were blamed on the All Burma Students Democratic Front and the remnants of the Burma Communist Party, which disintegrated in 1989 after its main fighting forces -- ethnic Wa and Kokang -- reached peace agreements with the government.
