Thai authorities said Tuesday they were hunting a man shown on security footage strolling into a packed religious shrine wearing a bright yellow T-shirt and leaving a backpack before an explosion killed at least 20 people, AFP reports.
The attack occurred on Monday in one of the Thai capital's most popular tourism hubs, ripping through a crowd of worshippers at the Hindu shrine close to five-star hotels and upscale shopping malls.
More than 100 other people were injured in the blast that left body parts, shattered glass and incinerated motorcycles strewn across the crushed concrete of a busy intersection.
