In this photo by Sakchai Lalit, a staffer at the Erawan Shrine in central Bangkok organizers garlands laid by visitors at Phra Phrom, the Thai version of the Hindu god Brahma. Wednesday marked the anniversary of the bombing of the shrine that killed 20 people and wounded 120.
The explosion occurred at evening rush hour as Thais and foreigners, most of them Chinese tourists, were gathered around the shrine, a Bangkok landmark at a busy intersection. Authorities have arrested two Chinese Uighurs, apparently part of a group seeking to avenge Thailand's forced repatriation of Uighurs, an ethnic Muslim minority, to China. The men have pleaded innocent.
