BANGKOK - Thai monks led prayers Wednesday for the reopening of Bangkok shrine where a blast killed 20 people, as police hunted a man shown on security footage calmly planting what is believed to be the bomb.
The bomb struck early on Monday evening as worshippers and tourists crowded into the Erawan shrine in the Thai capital's commercial heart, but no-one has yet claimed responsibility.
The unprecedented attack on the Thai capital left at least 11 foreigners dead, with Chinese, Hong Kong, Singaporean, Indonesian and a family from Malaysia among the victims.
More than 100 other people were wounded by a blast that shredded bodies and incinerated motorcycles at one of the city's busiest intersections.
Police said a second explosion at a Bangkok pier on Tuesday that caused no injuries may be linked, deepening fears for Bangkok residents with police conceding they do not know who was responsible.
Around a dozen Buddhist monks led prayers at the Erawan shrine as it re-opened early Wednesday while devotees - including tourists - genuflected and held joss sticks, and AFP reporter said.
A relative of the dead Malaysians had laid bundles of clothes at the shrine to represent the lost loved ones, according to a monk.
The shrine - a popular tourist attraction that typifies the kingdom's unusual blend of Hindu and Buddhist traditions - and its surrounding had already been largely restored.
Twisted iron railings were the only immediate sign of the carnage, which police believe was caused by a bomb made up of three kilogrammes of explosives and ball bearings.
One devotee had more reason than most to give thanks.
Tommy Goh, 56, a Thai-Malaysian from Penang, said only a delayed taxi from his hotel spared him from being at the shrine around the time of the blast.
"Every year I come down to this shrine, we were meant to be here around 6.50-7pm but the taxi didn't arrive from the hotel... so we went somewhere else," he told AFP.
"Ten minutes later and it could have been so different."
Police released images Tuesday showing a man, apparently young, slightly built and wearing a yellow T-shirt and dark shorts, walking into the shrine with a backpack.
In the video he calmly places the backpack underneath a bench and then walks away clutching a blue plastic bag and what looks like a smartphone.
The bomb exploded several minutes later, leading Thailand police to make the man their prime suspect.
A small explosion on Tuesday by a bridge at the city's Chaopraya river has been tied to Monday's bomb.
Colonel Kamthorn Ouicharoen, of Thai bomb squad police confirmed the bridge bomb was same type as that detonated at the Erawan Shrine "It's exactly the same, the equipment used to make it, the bomb size," he said.
"Police will resume collecting evidence this afternoon," he added.
Thailand has experienced a near-decade long political crisis that has seen endless rounds of street violence.
But never anything on the scale of Monday's bomb.
A festering insurgency by Muslim rebels in the Thai south has claimed 6,400 victims, but is a highly localised conflict.
