The canal where the accident took place was created more than a year ago from a branch of the Vam Thuat River, a tributary of the Saigon River. It is surrounded by 70-centimeter barriers but in the area where the two children had drowned, a three-meter section is missing.
The kids, who were brother and sister, were playing together just before they fell into the water. It was their mother and neighbors who discovered their bodies in the canal after hours of searching.
"If the barrier had not been missing, the kids could not have fallen into the canal," a local named Nguyen Duc Thang said.
