Thai police on trail of backpack bomber who killed 20 in Bangkok shrine blast
As images reveal man in yellow T-shirt as chief suspect behind Bangkok blast, Hong Kong mourns two of its own who were among the 20 killed

Less than 24 hours after a deadly blast gutted the core of central Bangkok, Thai police said last night that they believed a man wearing a yellow T-shirt and carrying a backpack had set off the explosion that killed 20 people and injured 125.
Their initial findings came as Hong Kong reeled in shock that two of its own - young female friends enjoying their summer break in the hip tourist spot - were among the dead.
The carnage also claimed the lives of four mainlanders while around 20 suffered injuries, including a 10-year-old girl whom Thai media reported was in a coma. With such casualty figures, Monday's attack outside the Erawan Shrine beloved by East Asians was one of the deadliest in recent years for Chinese nationals on foreign soil.
Earlier in the day, National Police Chief Somyot Pumpanmuang said that police were "not ruling out anything, including Thai politics and the conflict of ethnic Uygurs who, before this, Thailand sent back to China".
Thailand forcibly returned 109 Uygurs to China last month.
