Winai Petploy, a rescue worker who carried away the remains of the dead, said authorities discovered two unexploded bombs inside the Erawan Shrine after he had arrived. The bombs were in small travel bags, he said.
If so, certainly points to terrorist intent.
I survived a truck bombing at a hotel (used as an NCO billet) where an airline bag left on the sidewalk was basically a Claymore timed to sweep responders and those assisting injured.
(Metropole Hotel, Saigon, Vietnam, 4 December 1965.)
But at this point nobody / no group has claimed responsibility and many statements are confused.
BTW, Erawan is dedicated to Phra Phrom, a representation of Brahma, therefore is Hindu, no? Built at the time of the old Erawan hotel, replaced by the Grand Hyatt Erawan. But visited by many others, including Buddhists and just visitors. The location may have been chosen mainly for the crowd aspect.
