Residents in Alley 17 on To Ky Street said they heard repeated shouts at about 1 am and rushed outside to find a house engulfed in flames. Attempts to put out the fire failed because the house was locked from the inside.
After receiving the report, police dispatched fire engines and officers to the scene. The blaze was brought under control a few minutes later.
Police found three people dead inside the house, a 44-year-old woman, her 14-year-old daughter and her six-year-old son.
The house, about four metres wide and less than 10 metres long, is located deep inside an alley at the foot of Cho Cau Bridge. The husband was not at home when the fire broke out.
