Rescuers search for the bodies of the children stuck inside the rubble.
Two children are dead after a gas cylinder explosion collapsed a house in Hanoi early November 3.
At around 5:30 a.m., the three-floor house in Hanoi's Bach Khoa Ward fell down following a huge sound.
After neighbors rushed to the scene, they took Tran Nhat Minh, the 43-year-old husband, and Nguyen Thi Thu Ngan, the 37-year-old wife, out of the wreckage.
The couple, who suffered serious burns on their faces, chests, arms and legs, was rushed to a local hospital.
Rescuers arrived at the scene to search for the couple's daughter and son 14-year-old Tran Ngoc Tam and 7-year-old Tran Duy Anh who were stuck inside the rubble.
An excavator was used to shovel the rubble, and the body of the boy, Anh, was found at around 10 a.m.
Two hours later, the body of the girl, Tam, was recovered.
Initial investigations showed a gas cylinder in the house exploded and leveled the structure to the ground.
As soon as Ngan recovered at the hospital, she told her family she smelled something strange like gas in her house early in the morning.
Minh reportedly opened a door when Ngan turned on the gas cooker to check if something went wrong with the gas cylinder, and it exploded.
