Four middle school students died in floodwaters, which were caused by downpours, in the south-central province of Khanh Hoa on Monday.
The first three victims, Nguyen Xuan An Khang, Pham Minh Huy and Tran Minh Trung, all in seventh grade, were playing along Nha Trang – Dien Khanh Street when they fell into a construction hole, causing them to drown on Monday afternoon, Nguyen Ngoc Tuan, a chief from the local police department, said on Tuesday.
The hole – thirty meters long, four meters wide and two meters deep – was dug by Phuc Son Corporation and filled with water from the rain that had come down since Sunday, according to officials.
There were no warning signs around the construction area, they added.
The body of the fourth student, 11-year-old Nguyen Thi Xuan Quyen, was found on Tuesday afternoon after she went missing on Monday, said Dinh Gia Bao, head of the education bureau in Dien Khanh District.
Quyen had been riding her bicycle to school on a new route which runs along a canal for about ten days before the tragedy happened, her family said.
She was washed away by the strong torrent of floodwater, they added.
The heavy rain continued on Wednesday morning and caused serious flooding in many areas in Khanh Hoa, threatening the lives of many local residents, especially students and young children.
