Although Thailand is predominantly Buddhist, Hinduism has an influence on its religious practices and language. The shrine's location adds to its popularity, offering an open-air place for prayer amid the capital's gleaming shopping malls and five-star hotels.

On Wednesday morning, a stream of people arrived at the shrine, kneeling in prayer, lighting incense and placing flowers at the site where 36 hours earlier the explosion scattered body parts across one of the capital's busiest intersections. Buddhist monks in saffron robes joined members of the public to chant prayers.

Among those who paid respects was an office worker, Nuansupha Sarunsikarin, who expressed shock and sadness over the attack.

"I'm depressed for those innocent people who had to pay for something they're not involved with and now have no chance to live their lives," Nuansupha said.

Thai authorities identified six victims as Thai and four as Malaysians, along with four Chinese, two people from Hong Kong including one British citizen, one Indonesian and one Singaporean. Two victims remain unidentified.

Bangkok was rattled by a second blast Tuesday at a popular ferry pier which exploded in the Chao Phraya River and caused no injuries. Prawut said the explosion at the Sathorn Pier frequented by river ferries and tourist boats also was caused by a pipe bomb and could be related to the shrine attack. Security video showed a sudden blast of water over a walkway at the pier as bystanders ran for safety.

Thailand has seen many violent attacks in recent years, particularly in a more-than-decade-long insurgency by Muslim separatists that has killed over 5,000 in the country's south. Those attacks have never reached the capital, however.

Bangkok has seen politically charged violence in the past decade; the deadliest, in 2010, killed more than 90 over two months and was centered on the same intersection where Monday's bomb went off. But none of those attacks included a bomb that seemed intended to produce mass casualties.
