The U.S. Embassy in Bangkok issued the following message on Sep 18.
This message alerts U.S. citizens traveling to or residing in Bangkok that media reports indicate that as many as 30,000 supporters of the United Front for Democracy Against Dictatorship (aka UDD or “Red-Shirts”) will rally at Sanam Luang and plan to march to the residence of Privy Council Chair General Prem Tinsulanonda on Saturday, September 19.
In order to maintain peace during the rally, the Royal Thai Government plans to invoke the Internal Security Act (ISA) in Dusit District (to include the Dusit Palace, Government House, Sanam Luang, and the area near General Prem’s residence) from Friday, September 18 to September 22. This may mean that armed troops will join police on the streets to maintain order.
Media reports indicate that over 5,000 soldiers and police officers have already been deployed to the Dusit District in anticipation of the rally.
We wish to remind American citizens that even demonstrations intended to be peaceful can turn confrontational and possibly escalate into violence. American citizens are urged to avoid the area of Sanam Luang and to exercise caution if within the vicinity of any demonstrations.
