Here are my images from the time I spent at Silom last night. I arrived not long after what authorities say was an M79 grenade exploded near the Dusit Thani hotel, in an area where pro-government demonstrators had been rallying.
The blast that happened here was one of a series of explosions that killed at least one person and injured at least 75. (Various sources are providing different numbers at this point.)
I was concentrating on TV and radio work, so I didn’t have much time to snap many images. But these photos should give you a sense of what the scene looked like in the hours after the blast occurred.
For commentary on the evening, I suggest checking out this blog post from Andrew Marshall, who was there last night.
UPDATE: As Andrew points out, you can find some images from last night in this New York Times slide show.
