All but one of the victims has been identified, according to the Prime Minister Han Duck Soo, who pledged that the government would do everything in its power to help the bereaved families.
The government will do its best to find out the cause of the accident and improve the necessary systems, Han said.
Police Chief Investigator Nam Gu Jun told the media that we are examining CCTVs to find out the exact cause of the accident, and that we will continue to question more witnesses, including nearby shop employees. A man who survived the crowd surge said he could still see people dying in front of me. The people started pushing from behind, it was like a wave - there was nothing you could do, Nuhyil Ahammed told the BBC.
