U Lwin, the spokesman for the National League for Democracy Party (NLD), said today (Monday) that the supporters were waiting by the side of the road near Mandalay Sunday, waiting for the Nobel Peace laureate to arrive, when the incident occurred.
Members of the pro-government Union Solidarity Development Association packed about a dozen vehicles with people and shouted at the bystanders to run for their lives or they would have to pick up corpses, as they drove along the shoulders of the road.
Aung San Suu Kyi and the NLD have already complained of increasing harassment from the military government, particularly of the thousands of supporters who flock to see her.
The USDA was formed as a social organization and claims about 19 million members.
