According to local witnesses, at 2pm plumes of black smokecould be seen billowing from the kitchen area of the Burger King on Bui Vien street and they raised the alarm. The blaze caused residents and visitors to flee the area in panic and a crowd of people flocked to the streets. When the fire was detected, almost all staff ran out of the shop but two elderly people were trapped on the upper storey and were unable to escape as the shop had only one exit which was blocked with smoke and flames. District 1 firefighters rushed to the scene to rescue the two elderly people. The fire was brought under control within 15 minutes. The cause of the incident is still under investigation.
