There is a palpable sense of shock in Thailand, as news of a bomb blast in the capital Bangkok spreads.
At least 12 people died in the explosion at Erawan Shrine, and eyewitnesses have reported scenes of carnage and devastation as emergency teams attend to the wounded.
BBC News has spoken to a number of people who saw and heard the blast.
Richard Sri-kureja was walking to a mall next to the shrine when the bomb was detonated.
"There was total chaos. They blocked off the area, everyone was running in totally different directions," he told the BBC.
"About five minutes later police and ambulances rushed to the scene. I counted around 20 ambulances.
"That area is usually very, very crowded as it's in the middle of the city and it's usually very packed.
"A local hotel is full of injured patients. I saw a family that was bleeding badly.
"Everyone was trying to help as much as they could. Other people were taking photos."
