YANGON (Reuters) - An explosion outside City Hall in military-ruled Myanmar's main city, Yangon, on Thursday injured at least one person, witnesses told Reuters.
Police immediately sealed off the area, a focal point of major protests a year ago against decades of army rule in the former Burma.
Thursday is the eve of the anniversary of a military crackdown on the protests in which at least 31 people were killed.
