At around 10 a.m., an explosion occurred, rumbling the ground, shaking the walls and shattering the windows of a 5-story house that was also a restaurant, on Yen Phu Street, causing it to collapse.
There were no customers at the restaurant at the time, only two employees.
Shattered walls fall over objects inside the restaurant. However, the beams that support the house remain intact.
Firefighters use ladder trucks to gain access to higher floors of the building.
Five people were taken to the St. Paul Hospital, a representative of Ba Dinh District said. The explosion might have been caused by a gas leak, they added.
