The blast went off in front of Erawan Shrine, a Buddhist shrine and major tourist attraction in the city's major shopping district. There's also a video (below) from a local camera that caught the moment the explosion went off.
Lt. Gen. Prawut Thavornsiri told the Agence France-Presse that:
"I can confirm it was a bomb, we can't tell which kind yet, we are checking."
The explosion was so powerful that it left parts and debris from approximately five different motorcycles scattered across the street as well as bloodstains up on the second story of a nearby shopping mall.
No further details have been released, but our hearts are with all those affected by this tragic event.
