YANGON, Myanmar (Burma)- An explosion on Tuesday at dawn rocked the office of a government-backed social welfare group whose members have been accused in attacks against Myanmar's pro-democracy opposition, witnesses said.

The witnesses, who spoke on condition of anonymity for fear of official reprisal, said the blast occurred at the office of Union Solidarity and Development Association office in the northern Yangon suburb of Shwepyithar. No casualties were reported.

Residents in Shwepyithar said riot police and security officials swarmed into the area after the explosion.

No further details were immediately available, and there were no immediate claims of responsibility. The government has not blamed any group for the bombing...

Though they have not blamed any group yet I wouldn't be surprised if the military government staged the bombing itself to help create a case against the National League for Democracy. It would be silly really for them to do that, what with all of the hideous crimes they have committed against the Burmese people. I don't believe there is any violence that could come from any opposition group that could compare to what the military has done.
