9 others survived but some were severely injured
A man and a woman were killed when a house of around 30 years old collapsed in Hanoi early on Thursday morning.
The four-story house in the Old Quarter reportedly fell down at 3:15 a.m. when there were 11 people inside.
Seven managed to escape, two of them with injuries.
Hundreds of police and soldiers were sent to rescue the other four. But only two of them survived and were rushed to hospital.
The bodies of the two victims had been recovered by noon.
The house, of more than 50 square meters, was built in the 1980s. Police said it did not have a strong foundation.
There was a shop selling pork pie on the ground floor. Its employees slept upstairs.
Hanoi authorities have asked people living nearby to move as the collapse has left cracks on at least one house next door.
They said nearby construction activities and heavy rains in recent days are possible causes. Investigation is going on.
