From Michael Yon's Facebook 04:00CST -
Message from Irving Paul Knightly: "SET (Thai stock exchange on Ratchada) is now burning, and a campaign of arson now seems to be underway. Fires have been set at Siam Square shopping center."
Yon- "There are at least two substantial fires in Bangkok that I can see. I don't see the actual fires or what is burning but does not appear to be smoke only from tires. Something serious apparently is burning. A journalist just told me that 4 journalists have been shot today and one died. I do not know if this is true. He said we are being targeted. I do not know if this is true but it seems so." Yon's background- Wikipedia, Wired Magazine
